Development of lignin-based dispersants for hybrid Alkyd/latex paint coatings: functionalization, stabilization, and performance evaluation

This project is a collaboration between Lakehead University in Ontario, Canada, and Åbo Academy in Finland. In this research, we focus on replacing harmful chemical ingredients, dispersants, with sustainable, renewable, plant-based materials to develop more environmentally friendly paints. Conventional paints, particularly those formulated with alkyd resins, often release pollutants or harmful volatile organic compounds (VOCs) into the air and depend on synthetic chemicals that pose environmental risks and increase production costs. Our goal is to study the potential of lignin, a natural biopolymer found in plants and a byproduct of the pulp and paper industry, to be used as a safer, biodegradable alternative to help mix and stabilize paint components. By using lignin, we try to modify paints that are not only better for the planet but also affordable and high-performance. This research will benefit both academic and industrial partners by contributing to greener manufacturing practices and supporting innovation in sustainable materials.
