The NWSCT is planning IN-PERSON meetings for the current
2023-2024 meeting season.
Meetings are typically held the second Tuesday, October-April.

April Meeting

Tuesday, April 9th

This is our Annual Education Symposium and features presentations from students at North Dakota State University's Department of Coatings and Polymeric Materials. The meeting will begin with an overview of current NWSCT business, including a vote for nominated executives for the NWSCT for the 2023-2024 season. The meeting is being held on Tuesday, April 9th, 11:30am-1:30pm at Sherwin Williams in Minneapolis, MN (1101 S 3rd St, Minneapolis, MN 55415 MAP) and will include lunch which the cost is $25 for members and $30 for non-members. Registration must be made by/before Thursday, April 4th.

There will be three (3) presentations titled, "Multisubstrate adhesion performance of pressure-sensitive acrylic adhesives with plant oil-based monomers" presented by Bohdan Domnich, PhD Student and "Advancements in Anti-Biofouling and Anti-Icing Elastomers: A Study on Elastomer- Additive Compatibility" presented by Maryam Safaripour, PhD Candidate and "Artificial Intelligence and Machine Learning in Design of Coating Materials" presented by Bakhtiyor Rasulev, Associate Professor.

Abstracts:
Pressure-sensitive adhesives (PSAs) are widely used in food packaging, electronics, automotive industry, medical devices, and construction. The unique properties of this type of material, such as low glass transition temperature and high tackiness, allow the formation of joints between various substrates with the application of light pressure for a short period of time. In the current research, we partially substituted commercial acrylic monomer used for PSA synthesis (2-ethylhexyl acrylate) with plant oil-based acrylic monomers (POBMs) developed in our research group. POBMs have extremely low water solubility, contain vinyl and allyl functionality, and can undergo free-radical polymerization. The POBMs yield homopolymer with low Tg (-80 to -90 ºC), while the allyl group remains intact and can be used for cross-linking via autoxidation.

Silicone elastomers, when combined with oil, act as self-lubricating coatings that prevent ice and biofouling adhesion. These coatings possess a combination of properties, including hydrophobicity, low surface roughness, coating elasticity, and the presence of a lubricating layer, enhancing their effectiveness in effortlessly repelling such agents. However, investigating the impacts of the compatibility between elastomer and oil on the bulk and surface-specific properties of these coatings and understanding how these impacts influence the coatings' effectiveness against icing and biofouling, presents a complex challenge. To address this complexity, we developed clearly defined and thoroughly characterized silicone-based elastomers incorporating free silicone oils. This effort aimed to better understand the effect of compositional variables on elastomer-oil compatibility and how this factor modifies the coating properties, potentially altering their anti-icing and anti-biofouling capabilities.

The exponential growth and success of Artificial Intelligence (AI) and Machine Learning (ML) has resulted in their application in all scientific domains including material science. AI/ML is becoming an important tool in the field of materials, attributed to its power to predict materials properties, design de novo materials and discover new mechanisms beyond intuition. As the structural complexity of novel materials soars, the material design problem to optimize physico-chemical and mechanical behaviors can involve massive design spaces that are intractable for conventional methods. In this talk we will discuss the state-of-the-art AI/ML methods, their potential and application in coating research and design. The focus on four aspects of the AI/ML workflow will be discussed: (1) data collection, (2) encoding of multi-component material, i.e. feature representation, (3) model generation and validation, and (4) virtual libraries design for high-throughput screening to find novel materials. Several case study examples will be discussed, where structure-property ML models developed for coating materials to predict various properties.

Speaker Biographies:
Bohdan Domnich graduated from Lviv Polytechnic National University (Ukraine) in 2019 with a bachelor’s degree and in 2021 with a master’s degree in Chemical Technologies and Engineering. He joined the Department of Coatings and Polymeric Materials as a visiting researcher in December 2020 within the USURE 2020 program. In August 2021, Bohdan started his Ph.D. at CPM. His research focuses on the synthesis and characterization of permanent and pressure-sensitive latex adhesives for multi-substrate applications.

Maryam Safaripour received both her M.S. and Ph.D. in Agroecology from Iran. She first joined the Department of Coatings and Polymeric Materials (CPM) as a visiting researcher in June 2019 working on assessing the environmental impact of bio-based materials to align with sustainability objectives. During this time, she worked alongside Professor Dean Webster's team on a project that explored the concept of amphiphilic critical concentration for use in anti-icing and anti-biofouling coatings. Maryam started her Ph.D. at CPM in January 2021 under the guidance of Professor Dean Webster. Her current research focuses on the development of elastomers containing additives for anti-biofouling and anti-icing surfaces, with a special emphasis on the compatibility between the elastomer and the additives.

Prof. Bakhtiyor Rasulev leads a Computational Polymer Science Lab at the Department of Coatings and Polymeric Materials in North Dakota State University. Before joining NDSU he was working at the Interdisciplinary Center for Nanotoxicity (Jackson, MS), directed by Distinguished Professor Jerzy Leszczynski. He received his PhD from Academy of Sciences, Uzbekistan. Prof. Rasulev’s research covers a range of topics in Artificial Intelligence and Machine Learning (AI/ML) of materials, structure-activity relationship studies to predict biological activity, physico-chemical properties and toxicity of various organic compounds, polymers, coating materials and nanomaterials. For this purpose, he applies AI/ML methods, quantum-chemical and cheminformatics methods.

January 2017 Winter Outing

This year the NWSCT broke new ground by hosting an event at Summit Brewing in St. Paul on January 10th. This event included a tour of their facility, dinner and of course beer sampling. It also allowed us to gain insight into a very important batch making process. Based on the turnout and enthusiasm for the event it will probably not be the last time that we host an event like this.

Annual Education Symposium Abstracts

Electrochemical Investigation of Polyester Powder Topcoats and Application to Magnesium-Rich Primers for Corrosion Protection Systems

Casey Orgon

Abstract

Environmental concerns in the coatings industry have led to strict regulation of the use of conventional solvents used in coatings formulations. Powder coating systems avoid this issue by fluidizing finely ground particles in air for efficient transfer to a substrate. Once cured, these coatings can provide high performance protection and have already proven themselves in many extreme environments. In partnership with Valspar and The United States Air Force, NDSU has begun research on powder coatings for corrosion protection. Electrochemical impedance spectroscopy has been used to assess barrier properties of polyester powder topcoats crosslinked by TGIC and Primid chemistries. In addition, the feasibility of applying powder topcoats to Mg-rich primers has been explored with promising results. Combining these coatings can provide a corrosion protection system with high barrier properties of the powder topcoat and cathodic protection by the Mg-rich primer.


 

Vanillin: A Biobased Crosslinker for Epoxy Thermoset Coatings

Alison Rohly

Abstract

With an increasing need for biobased replacements of petrochemical materials, lignin offers significant potential in strength, durability, cost, and functionality. Lignin can be depolymerized to form small molecular weight compounds, the most abundant being vanillin. Although little research has been done, vanillin offers great potential as a crosslinker in coatings systems due to its unique functionality. The current research is therefore focused at incorporating lignin-derived vanillin into epoxy thermoset systems as a biobased crosslinker.
