Studies on the preparation of hydrolyzed starch-g-PAN (HSPAN)/PVA blend films––Effect of the reaction with epichlorohydrin

Properties of biodegradable blend films based on fish myofibrillar protein and polyvinyl alcohol as influenced by blend composition and pH level

“…In addition, the improved mechanical properties of FMP/ PVA blend films plausibly resulted from increase in crystallinity in the film due to increased crystallizable PVA. Similar result had been reported for hydrolyzed starch-g-PAN (HSPAN)/PVA blend film, in which the superior TS value was found at HSPAN/PVA ratio = 80:20 (Kim et al, 2002). Methylated corn starch and PVA blend film had the increases in TS and EAB value with PVA incorporated from 20% to 100% when compared with film without PVA (Gouhua et al, 2006).…”

“…The increase in solubility was probably due to the increase in proportion of hydrophilic compound, PVA. Kim et al (2002) found the higher solubility of hydrolyzed starch-g-polyacrylonitrile (HSPAN)/PVA blend film with increasing PVA content. However, the solubility of the blend system between Amaranthus cruentus flour and PVA was considerably reduced for film blend with more than 10% PVA (Elizondo et al, 2009).…”

Preparation and characterization of surface crosslinked TPS/PVA blend films

“…Crosslinking agents, such as epichlorohydrin (Kim, Na, Park, Yoon, & Ihm, 2002;Sreedhar, Chattopadhyay, Karunakar, & Sastry, 2006), boric acid (Yin, Li, Liu, & Li, 2005), borax (Sreedhar, Sairam, Chattopadhyay, Syamala Rathnam, & MohanRao, 2005), glutaraldehyde (Pal, Banthia, & Majumdar, 2008;Ramaraj, 2007;Yoon, Chough, & Park, 2006b) and tetraethylene glycol diacrylate (Marques et al, 2006), were used to react with the hydroxyl groups in starch to create intermolecular linkages so that macromolecular networks were formed. These crosslinking agents were usually added into aqueous solution of starch/PVA mixture and then the crosslinked films were prepared by casting method.…”

Performance properties and antibacterial activity of crosslinked films of quaternary ammonium modified starch and poly(vinyl alcohol)

“…PVA/starch blend is suitable to be used as biodegradable packaging and agricultural materials [7]. Their physical properties can be improved by adding plasticizers such as glycerol [7,8], by using chemically modified starch [9,10], by adding crosslinker [3,11], or by preparing biodegradable nanocomposites [12,13].…”
