“…This is due to their hydrophilic nature and thus their sensitivity to moisture content, a factor that is difficult to control. In order to improve mechanical properties and water resistance, starch has been modified (Morikawa & Nishinari, 2000;Curvelo, de Carvalho, & Agnelli, 2001;Mani, Tang, & Bhattacharya, 1998;Rutot, Degee, Nayaran, & Dubois, 2000;Matzinos, Tserki, Kontoyiannis, & Panayiotou, 2002;Mani & Bhattacharya, 2001;Dufresne, 2006) by blending with synthetic or natural polymers and modified with aliphatic polyesters, such as PCL, poly (hydroxyl butyrate), poly lactic acid and poly (glycolic acid) (Namazi & Dadkhah 2008;Wang & Gross, 1998). Among them poly (e-caprolacton) is a particularly promising polymer.…”
