ABSTRACT

In recent years, many researchers and scientists have paid attention to develop a variety of advanced and hybrid polymeric materials for their industrial applications (Liu et al., 2009) due to their unlimited availability, much higher specic strength, lower cost, and their potential applications such as biomaterials, drug delivery (Dong et al., 2008; Liu et al., 2011; Das and Pal, 2013), coatings, lms, membranes, drilling techniques, pharmaceuticals and foodstuffs (Klemm et al., 2005; Hiltunen et al., 2012), packaging, bioenergy, bioplastics, and aerospace industry (Alila et al., 2009; Akar et al., 2012; Bao et al., 2012; Thakur et al., 2013). Of these materials, one of the most important is graft copolymer (Liu et al., 2011; Thakur et al., 2013). Graft copolymers by denition consist of a long sequence of one polymer (often referred to as the backbone polymer) with one or more branches (grafts) of another (chemically different) polymer (Gowariker et al., 1986; Odian, 2002). Graft copolymers can associate to form micelles in selective solvents, which are thermodynamically good solvents for one of the components and comparatively poor solvents for the other (Tang et al., 2007; Gao et al., 2008).
