BIODEGRADABLE FILM CONTAINING NANO COMPOSITE POLYMER MATERIAL HAVING HIGH DISPERSITY AND DISPERSION STABILITY BY DISPERSING NANOSIZED MONTMORILLONITE WITH LIPOPHILICITY
BIODEGRADABLE FILM CONTAINING NANO COMPOSITE POLYMER MATERIAL HAVING HIGH DISPERSITY AND DISPERSION STABILITY BY DISPERSING NANOSIZED MONTMORILLONITE WITH LIPOPHILICITY
PURPOSE: An environment-friendly biodegradable film is provided to be manufactured by low cost together with having excellent thermal properties and mechanical properties enough to use for disposable products.;CONSTITUTION: An environment-friendly biodegradable film is manufactured by molding a composition containing 40-90 weight% of nano-sized sodium montmorillonite, and 10-60 weight% of modified thermoplastic starch to a film. The size of the sodium montmorillonite is 10-55,000 nm. The sodium montmorillonite is obtained by purification of montmorillonite in sodium chloride aqueous solution. The modified thermoplastic starch is manufactured by mixing 20-30 parts by weight of plasticizer, 2-5 parts by weight of compatibilizer, and 0.2-0.5 parts by weight of an initiator into 100.0 parts by weight of the starch.;COPYRIGHT KIPO 2012
