Cellulose-based plastic films were prepared by acylating cellulose in homogeneous media under microwave irradiation with fatty acyl chlorides containing either saturated or unsaturated chains of various lengths (C-12 to C-18). The resultant cellulose esters were analysed by FTIR and H-1 NMR spectroscopy to confirm their structure and to determine their degree of substitution. Some of the cellulose fatty esters were then converted into polymer films by casting. The mechanical properties of these films were determined, including their elastic modulus, tensile strength and tensile strain level. The hydrophobicity of the polymer films was determined by contact angle measurement with water. The mechanical and hydrophobic properties of the plastic films were then compared to those of commodity plastics.
