The demand for sustainable and non-toxic colour technologies is rapidly increasing across industries such as paints, coatings, textiles and cosmetics. Conventional colourants, including synthetic dyes and pigments, often raise environmental concerns due to toxicity, persistence and microplastic generation. This project explores an alternative approach based on structural colour, where colour is generated through nanoscale organisation of materials rather than chemical pigments to offer a route towards vibrant, durable and environmentally friendly colouration.
Inspired by natural systems such as butterfly wings, which produce bright colours through intricate internal structures, this PhD project will investigate how biodegradable polymers can be designed to form nanoscale building blocks and organised into materials that control light. The aim is to develop new types of pigment-free colour coatings that combine strong optical performance with sustainability.
The successful candidate will design and prepare polymer materials, study how their structure influences optical behaviour, and develop strategies to assemble them into ordered architectures that generate colour. The project will involve a combination of laboratory-based materials synthesis, advanced characterisation techniques, and exploration of scalable processing methods relevant to real-world applications.
This research has the potential to contribute to the development of next-generation sustainable colour technologies, with relevance to industries seeking environmentally responsible alternatives to conventional pigments. In addition, structural colour materials are of growing interest for applications in sensing and responsive optical systems.
The successful candidate will gain interdisciplinary training in polymer science, materials characterisation and photonic materials, and develop a broad skill set spanning fundamental research and applied materials development.
Applicants should bring a strong background in organic or polymer chemistry. Experience in materials science, soft matter, photonics or advanced characterisation techniques is desirable but not essential.
