John Worth is a researcher in the Bristol Composites Institute at the University of Bristol. His research is centred on the design, synthesis, and characterisation of highly porous polymeric materials and their composite membranes for hydrogen storage applications. His focus is on the relationship between polymer structure, porosity, and gas adsorption performance, with an emphasis on developing scalable, metal-free materials that address the challenges of energy storage and decarbonisation. His broader research interests encompass advanced materials characterisation, gas sorption analysis, and the integration of porous materials into sustainable energy technologies.
