HPMC being a biodegradable polymer

HPMC, being a biodegradable polymer, has also been used to prepare biocomposites. Several studies have been carried out to investigate the influence of different additives on the physicochemical properties of HPMC. Dogan et al. [179] investigated the influence of microcrystalline cellulose (MCC) filler in the HPMC matrix to improve the mechanical properties of HPMC films without affecting their water permeability properties. In a similar study, various types of cellulose derivatives, such as cellulose nanofibers (CENFs), cellulose nanowhiskers (CNWs), etc., were incorporated into the HPMC matrix to enhance its properties [180]. Rao et al. [181] prepared zinc oxide (ZnO) reinforced HPMC composites and investigated their structural, surface wettability, and antimicrobial properties. The HPMC/ZnO composites showed promising bacterial resistance. The contact angle was decreased when ZnO content was increased. Ghosh et al. prepared graphene oxide (GO) reinforced HPMC nanocomposite films using a solution casting technique. The content of GO varied from 0.02 to 1.3 wt.%. The results confirmed the formation of exfoliated HPMC/GO composites with enhanced mechanical properties (tensile strength, Young's modulus, and elongation at break) of HPMC film concerning GO loading. In addition, the thermal stability of HPMC/GO composites has improved compared to neat HPMC, which is ascribed to the excellent thermal stability of GO. Priya et al. [183] prepared chitosan nanoparticles and incorporated them into the HPMC matrix to form CSNP/HPMC composite films for food preservation applications. HPMC can also be used to prepare composite films with lipids which can be used to preserve food.
