Abstract：A simple solution blending technique was used in this study to disperse sulfonated nanocellulose whiskers(CNC-C)as reinforcing agents into polydimethylsiloxane(PDMS)matrix,a series of biobased nanocomposites with excellent mechanical properties were successfully prepared.The study delved into the specific effects of CNC-C content and its distribution in composite materials on microstructure,internal structure,and mechanical properties.Due to its high aspect ratio,excel-lent crystallinity,and mechanical strength,CNC-C significantly enhances the mechanical properties of polydimethylsiloxane(PDMS),demonstrating outstanding reinforcement and toughening effects.In addition,by combining the outstanding conductivity of graphene(GR)with a three-dimensional con-ductive network constructed from thermoplastic polyurethane(TPU),real-time monitoring of strain in thin film materials has been achieved.This practicce not only greatly expands the application scope of bio based nanocomposites in practical production and life,but also plays a key role in material re-placement cycles and cost savings.
