Abstract: Composite films were prepared by using latex of natural rubber as the matrix and cross-linked porous starch as the reinforcing phase,and the structure and properties of the composite films were investigated. The results showed that the roughness of starch particle surface and specific surface area increased when porous starch was crosslinked. With the increase of cross-linked porous starch loading,the tensile strength and tear strength of the composite films increased first and then decreased. The composite film possesses the best mechanical properties at the cross-linked porous starch content of 10 parts per hundred rubber( phr). The glass transition temperature( Tg),thermal stability and solvent resistance of composite film are improved,but the water resistance is lower than that of the pure natural rubber latex film.
