Liquid Repellent Thermoplastic Starch and Biopolyesters

Ihere are only a few recent studies on the fabrication and characterization of stand-alone bio-polymer nanocomposite films or coatings displaying Hquid repellent properties. Obeso et al. [23] developed a superhydrophobic surface by precipitation of poly(hydroxybutyrate) (PHB) on the surface of cellulose fibers of papers using a phase separation process. The same authors used a similar approach to synthesize biodegradable superhydrophobic poly (L-lactic acid) substrates in order to control cell adhesion. Superhydrophobic/superoleophilic porous poly (L-lactic acid) films were also prepared by Xue et al. for water-oil separation applications [24]. Yohe et al. [25] prepared 3D superhydrophobic materials from biocompatible
