Neutron diffraction assessment of metal-polymer composite coating

This beamtime proposal aims to resolve a fundamental scientific question regarding enhanced creep resistance in polyurethane (PU) coatings containing hollow ceramic microcores with TiO2 shells (HCM@TiO2 ). Specifically, we will test the hypothesis that these core-shell particles modify the polymer's
crystallinity, which may explain the composite's superior mechanical performance compared to pure PU. Neutron diffraction at ENGIN-X will provide definitive evidence of crystallinity changes, addressing this ongoing debate in polymer composite research. The environmental significance of this work is twofold: (1) The HCM particles are derived from fly ash waste, transforming an industrial byproduct into high-value additives while reducing landfill burden, and (2) The resulting durable coatings decrease marine hazards, maintenance frequency, significantly lowering lifetime CO emissions in marine and construction applications. This research directly supports: -The UK's Ten Point Plan through development of advanced materials for green maritime and offshore wind infrastructure -UN Sustainable Development Goals (SDG 12 for responsible production and SDG 13 for climate action) -The UK Industrial Decarbonisation Strategy by demonstrating waste valorization and extended product lifespans.
