COMPOSITE MATERIALS AND THEIR USES AS WELL AS METHODS FOR THE PREPARATION THEREOF

摘要

A reinforced composite material based on a polymer matrix with reinforcement particles embedded therein is proposed. The polymer matrix is based on a polymer with soft and hard domains, and the reinforcement particles comprise inorganic nano-platelets in the polymer matrix in a volume fraction in the range of 0.01%-50%, wherein the inorganic nano-platelets have a thickness in the range of 0.3-50 nm and preferably a length and/or width in the range of 5-500 nm, with the proviso that the largest length and width is at least twice as large as the thickness; as well as inorganic micro-platelets in a volume fraction in the range of l%-90%, wherein the inorganic micro-platelets have a thickness in the range of 10 nm-100 μm and preferably a length and/or width in the range of 100 nm-10 mm, with the proviso that the largest length and width is at least twice as large as the thickness. Also proposed are multilayer structures based on such layers, methods for making such multilayer structures and uses thereof.
