Abstract:
The research focused on synthesis and characterization of PVA-ether starch film has been conducted. This study is divided into 4 steps, such as separation of unsaturated fatty acids of candlenut oils by urea complexation methods, epoxidation reactions of unsaturated fatty acid with a peracid acid, alkoxylation reactions of fatty acid methyl ester epoxide with cassava starch and preparation of PVA-ether starch film. The ether starch was obtained by alkoxylation reactions of fatty acid methyl ester epoxide of candlenut oils with cassava starch. The PVA-ether starch film was prepared by mixing polyvinyl alcohol and ether starch of the synthesis to obtained PVA-ether starch films which could applied as bioplastic. The tensile strength of PVA-ether starch films was higher than PVA-cassava starch films. The tensile strength, strain and modulus young's of PVA-ether starch films were 6,07 MPa; 18,41%; 32,97 MPa and PVA-cassava starch films were 4,23 Mpa ; 13,64% ; 31,01 MPa respectively. Furthermore, the hydrophobicity of the film was carried out by water-resistance test where the PVA-ether starch films has a higher water resistance than PVA-cassava starch with value were obtained 81,36% and 32,31%, respectively.
