摘要:Functional and smart materials based on renewable resources and “green” processes have recently attracted enormous interests. Cellulose is one of most attractive polymers in nature. It can be extensively derivatised to form stable and strong stiff-chain homomolecular structures with hydrogel- or film-forming properties, which have the potential to be a robust and stable carrier, matrix, or scaffold component for the preparation of functional materials.

In this talk, the preparation and properties of cellulose/nanocarbon (carbon nanotube and graphene) composites would be introduced. These nanocarbon/cellulose composites can be applied as multifunctional sensors responding to different stimuli like tensile strain, liquids, environmental temperature, humidity, and others. Based on their smart structure and outstanding properties, the nanocarbon/cellulose composites are promising multifunctional biopolymer based materials worth for further investigation.
