Cellulose is a naturally occurring and extremely common polysaccharide with huge hydrogen bonding and functionalisation potential. The raw source is important with respect to the extracted cellulose structure, morphology, aspect ratio, allomorph, and other properties. Extraction will occur from various sources (such as cocoa pod husk or tunicates) prior to characterisation, analysis, and eventual functionalisation and incorporation into polymer matrices. Functionalisation will be key to ensuring compatibility in polymer systems, as cellulose is inherently hydrophilic. The interactions the functionalisation process imparts will be studied in an effort to improve, tailor, and potentially create stimuli responsive properties. The polymer matrices chosen will endeavour to be sustainable in nature. That being: bio based; renewable (non-petroleum based); biodegradable; environmentally friendly; or a combination of those listed (such as PLA, PCL, or bio(PE)). A personal aim is to broaden and develop the knowledge on a sustainable plastics future, using natural/renewable materials, to replace those used in current applications that are derived from non-renewable sources.

纤维素是一种天然存在的极其常见的多糖，具有巨大的氢键和功能化潜力。原料来源对于提取的纤维素的结构、形态、长径比、异形体和其他性质是重要的。在表征、分析、最终功能化和纳入聚合物基质之前，将从各种来源（如可可豆荚壳或被囊动物）提取。功能化将是确保聚合物系统相容性的关键，因为纤维素本身是亲水的。功能化过程所带来的相互作用将被研究，以努力改善、调整和潜在地创造刺激反应特性。所选择的聚合物基质将努力在本质上是可持续的。那就是：基于生物的；可再生能源（非石油基）；生物降解;环境友好型;或这些列出的组合（如PLA， PCL或生物（PE））。个人目标是拓宽和发展关于可持续塑料未来的知识，使用天然/可再生材料，取代目前应用中使用的来自不可再生资源的材料。
