A Novel Biocompatible Actuator Based on Electrospun Cellulose Acetate
Fullerene reinforced electrospun cellulose Acetate(CA) nano fibers based composite dry-type actuators were newly developed. Morphology of the electro spun fibers showed good dispersion of the fullerene within the nano fibers whereas XRD studies slight increase in crystallinity. FTIR spectra showed interactions between the hydroxyl moieties of fullerene with cellulose. Stress-strain curves showed substantial increase in tensile strength even with minute concentrations of filler. Our results show nearly three fold increase in tip displacement even with 0.5 wt% fullerenes under both AC and DC conditions. The efficiency of the actuators was also calculated from current-voltage diagrams.
