Mechanochemical activation of cellulose and its thermoplastic polyvinyl alcohol ecocomposites with enhanced physicochemical properties

Poly(vinyl alcohol) films reinforced with nanofibrillated cellulose (NFC) isolated from corn husk by high intensity ultrasonication

“…PVA is the most abundant synthetic water-soluble polymer with low cost, which has desirable properties such as water solubility, biocompatibility, and biodegradability, excellent chemical resistance, gas barrier properties, good thermostability, optical and physical properties (Guirguis & Moselhey, 2011;Mihaela Jipa et al, 2012;Ramaraj, 2007;Zhang et al, 2011). It has been studied as a polymeric matrix in the construction of nanocomposite films due to the improved versatility by incorporating nanostructures (Hubbe et al, 2008;Tang & Liu, 2008b). In this paper, the NFC was separated from corn husks with the high intensity ultrasonication.…”

“…Recently, many efforts have been made worldwide to develop environmentally friendly, low cost, renewable and biodegradable substitute materials from non-petroleum resources because the non-degradable plastics obtained from petroleum causes the environmental pollutions (Zhang et al, 2011). Nanofibrillated cellulose (NFC) is attractive reinforcing fillers in thermoplastic matrix materials due to their exceptional mechanical properties, such as low density, easy biodegradability, renewability, low cost, low thermal expansion and high strength (Dufresne, Cavaillé & Vignon, 1997;Fukuzumi et al, 2008;Habibi, Lucia & Rojas, 2010;Iwamoto et al, 2005;Jonoobi et al, 2010;Siqueira, Bras & Dufresne, 2010).…”

Biodegradation Behavior of Composite Films with Poly (Vinyl Alcohol) Matrix

“…Blending natural polymers and synthetic ones is a simple and practical way to produce new materials [3]. Among synthetic polymers poly (vinyl alcohol) is known to be biodegradable and it blends with natural polymers (such as cellulose, starch, chitosan, soy protein isolate, fish myofibrillar protein) having promising industrial applications in many fields, including packaging industry, because of their biodegradability, biocompatibility, chemical resistance and excellent physical properties [2,[4][5][6][7][8]. Bacterial cellulose (BC), biosynthesized by several bacterial strains from which the Acetobacter xylinum is the most studied, represents another valuable candidate for composite materials.…”

Structure and performance of Poly(vinyl alcohol)/wood powder composite prepared by thermal processing and solid state shear milling technology

“…[7,13]. Unfortunately, the PVA/biomass composites were prepared by solution methods because PVA has very strong intra-or intermolecular hydrogen bonds, and its melting point and decomposition temperature are very close [14,15], thus the thermal processing of PVA has been a worldwide challenge.…”
