The Waterborne Symposium 2025

Abstract

Lightweight, mechanically robust materials capable of high thermal transport and minimal electrical interference are critical for the protection of sensitive high power electrical systems. Polymer composites are an excellent materials solution for protection of such electrical components however their development is met with multiple challenges. For example, polymer-particle interactions, processability, thermal properties, innate particle properties, viscosity, dielectric properties and composite morphology are only a few considerations for material screening. Boron nitride (BN), a thermally conductive low-density ceramic, is a reasonable additive to develop polymer composite solutions due to its inability to conduct electrons and minimal impact on component weight. On the other hand, the polymer carrier material for such ceramic particles is equally important in the development of novel functional materials. The design versatility of benzoxazine (BOX) monomers and polymer precursors offer endless opportunities to tune matrix properties and particle-polymer interactions as well as processing methods. Herein we will discuss key considerations for optimal composite performance, current challenges and limitations toward the development of new materials to fulfill an industry need through the lens of BOX/BN polymer matrix composites.

Abstract

"Regulatory activity in both the EU and USA is targeting a large group of chemicals known as PFAS (per- and polyfluoroalkyl substances). As a result, formulators in many industries are working to replace additive powders based on PTFE and PTFE hybrids with alternative materials that provide the same level of performance.
This presentation will detail a unique nanocomposite approach to eliminate PTFE in surface additives by replacing PTFE with hard, inert, durable materials such as aluminum oxide and ceramics. Data will be presented to show that this portfolio of over 8 additives provides equal or (in most examples) improved surface durability (lubricity, scratch & abrasion resistance) without the use of PTFE."

Abstract

Sustainable products are designed to minimize negative impacts on the environment while meeting the needs of consumers. By choosing sustainable products, reduction of waste, conservation of resources, and improved performance may be achieved while protecting the planet for future generations. It is important to consider not only the use of sustainable materials but also the overall environmental impact of the product, including its production, application, and end-of-life disposal. Using examples from sustainable resin development, many of the considerations for defining sustainability and in developing eco-friendly waterborne coatings such as copolymer handprint vs. footprint, biobased vs. mass balance, and cost effectiveness vs. improved performance will be presented and discussed.
