Mechanically Robust Cellulose Film for Electronics Applications

This research investigates the utilization of cellulose nanocrystals (CNCs) derived from sugarcane bagasse for the development of biodegradable films. CNCs were extracted via chemical procedures and then integrated with polyacrylic acid (PAA) to create crosslinked cellulose (X-CNC) composites. Fourier-transform infrared (FTIR) analysis verified the elimination of lignin and hemicellulose, and scanning electron microscopy (SEM) images exhibited enhanced dispersion in the presence of PAA. Notably, the thermal stability and mechanical properties experienced enhancement with an optimal 10 wt% PAA concentration in CNC. However, higher concentrations demonstrated an adverse impact on these properties.
