Abstract
Laminar crosslinked starch composite foams were prepared from glyoxal crosslink-tapioca starch and used corn husks as reinforcement which formed by compression molding. Effect of silane coupling agent on properties of laminar crosslinked tapioca starch composite foam were investigated. Corn husk were treated with silane coupling agents, tetraethoxy silane (TEOS) at difference content (2%, 5% and 10%). It was found that there was no effect of silane treatments on water resistance and foam morphology of starch composite foams. However, from SEM micrographs show less interfacial space between starch and silane treated cornhusk than untreated corn husk starch composite foams. As increasing TEOS content, impact strength and flexural strength of the composite foams were increased due to interfacial adhesion between starch and corn husk were improved by action of TEOS.
