Study on the Properties of the organosilicon-acrylic resin/LDHs nanocomposite

Abstract

Abstract. The organosilicon-acrylic resin/LDHs nanocomposite was prepared from acrylate, organosilicon，Mg-Al-AA-LDHs，as well as emulsifier etc with emulsion polymerization methods. The samples prepared were characterized by optical , thermal and gas barrier capabilities testing, Results show the samples were nanocomposion ,which Tg was disappear, and changed the nature of the acrylic resin of the "hot sticky cold brittle" defects fundamentally; The degradation temperature of organosilicon-acrylic resin/LDH was 470ºC when LDH content is 3%, 77 ºC higher than pure organosilicon-acrylic resin. With the increase of mass fraction of namo-AA-LDHs, the light transmittance increased, the fog degree reduced, the oxygen transmittance reduced and the water vapor transmittance slightly increased.The namocomposites had excellent thermal properties, outstanding optical and gas barrier properties.
