PhD Studentship: Materials-reinforced multifunctional coatings for built environments

Overview

This PhD studentship at the University of Exeter develops protective coatings for porous construction materials such as concrete, brick and wood. These materials are valued for strength, durability and thermal mass, but water ingress can cause surface degradation, internal cracking, frost damage and biological colonisation. Prolonged moisture makes them vulnerable to mould, which speeds structural decay, harms indoor air quality and poses health risks. Conventional surface treatments often rely on harmful chemicals such as PFAS, which raise environmental and regulatory concerns, so non-toxic alternatives are needed.

The project explores adding 2D materials, such as graphene and post-graphene structures, to PFAS-free formulations to create multifunctional coatings that are water repellent, breathable and resistant to mould. The work covers synthesis and functionalisation of 2D materials, development and optimisation of coating formulations and application methods, and performance testing including water contact angle, breathability, absorption, biological resistance and environmental chamber tests.
