significant health risks to building occupants. Moisture exposure to outdoor surfaces can also cause aesthetic damage, which gradually reduces the overall performance of the building and leads to significant maintenance and restoration costs. While traditional surface treatments are often applied, many conventional formulations rely on harmful chemicals, such as perfluoroalkyl and polyfluoroalkyl substances (PFAS), which raise environmental and regulatory concerns. As the construction sector increasingly prioritises sustainability, occupant health, and long-term durability, there is an urgent need for innovative, non-toxic protective coatings capable of preserving porous materials in both interior and exterior applications.
The research project aims to explore the integration of 2D materials, such as graphene and post-graphene structures, into PFAS-free formulations to develop multifunctional coatings for porous construction materials that provide hydrophobicity, breathability and anti-mould properties. The project will involve synthesis and functionalisation of 2D materials, development and optimisation of coating formulations & application methods, and comprehensive performance tests, including water contact angle measurements, breathability tests, absorption tests, biological resistance assays, and environmental chamber tests. This comprehensive testing will evaluate the coatings' effectiveness in improving moisture resistance, preventing mould growth, and enhancing the durability of porous materials in both indoor and outdoor environments.
