- Abstract
A novel, hybrid polymer composite wherein hydrophilic nanocrystalline cellulose (NCC) and hydrophobic lignin particles are reinforced into hydrophobic acrylic fiber based polyacrylonitrile (PAN) matrix is fabricated by the spin-casting technique. The discrete and synergetic influence of NCC and lignin on the PAN matrix was compared and studied on the basis of the assessment of the tensile properties of the composite films. It was observed that incorporation of NCC and lignin in the ratio of 50:50 into the PAN matrix enhanced its tensile strength and Young's modulus by 55% and 223% respectively. Individual comparison of FTIR spectra was performed to understand the structural aspects of neat PAN and PAN composite films incorporated with NCC, lignin, and blends of NCC and lignin. Further, the composite films were assessed for physical properties such as density, viscosity, and contact angle. The impact of NCC and lignin loading on the surface morphology of the PAN matrix has been evaluated using SEM imaging tool. The thermal stability behaviour of the neat PAN film and PAN composite film was comprehended using TG analysis.
