Increasing environmental awareness and growing shortage of fossil resources are prompting scientists and industry to develop bio-sourced materials that have the potential to replace toxic or non-biodegradable materials while offering similar or enhanced properties. Among the available biopolymers, cellulose is both the most abundant and sustainable while possessing outstanding physical properties such as high mechanical resistance and low density. Particularly, cellulose nanocrystals (CNCs) make attractive building blocks for the design of green nano-composites, particularly thin functional films replacing current petrochemical-resourced polymers in lubrication, 3D printing and sensor applications.The aim of the project is to explore the chemistry-structure-function relationship of various synthesised forms of CNCs, an exciting new area of research with significant potential industrial application. The student will receive training in a broad spectrum of techniques ranging from AFM, rheology, surface deposition (spin and dip coating), QCM, NMR and spectroscopic techniques available in SPS, alongside working with collaborators at large-scale neutron and X-ray scattering facilities in Oxfordshire and France.

环保意识的增强和化石资源的日益短缺正促使科学家和工业界开发生物源材料，这些材料有可能取代有毒或不可生物降解的材料，同时提供类似或增强的性能。在可用的生物聚合物中，纤维素是最丰富和可持续的，同时具有出色的物理性能，例如高机械强度和低密度。特别是，纤维素纳米晶体 (CNC) 为绿色纳米复合材料的设计提供了有吸引力的构建模块，特别是在润滑、3D 打印和传感器应用中取代当前石化资源聚合物的功能薄膜。该项目的目的是探索化学-各种合成形式的 CNC 的结构-功能关系，是一个令人兴奋的新研究领域，具有巨大的工业应用潜力。学生将接受广泛的技术培训，包括 AFM、流变学、表面沉积（旋涂和浸涂）、QCM、NMR 和 SPS 中可用的光谱技术，同时与大规模中子和 X 射线散射方面的合作者合作牛津郡和法国的设施。
