BIODEGRADABLE POLYMER COMPOSITES HAVING IMPROVED MECHANICAL PROPERTIES

摘要

The present invention is a matrix of a first polymer comprising a biodegradable polymer; A second polymer dispersed in the matrix to form a dispersed phase; And anisotropic particles arranged in the interface between the matrix of the first polymer and the dispersed phase of the second polymer or the matrix of the first polymer, wherein the anisotropic particles are biodegradable, which is a mixture of organic clay and natural clay. It relates to a polymer composite. According to the present invention, as anisotropic particles, which are a mixture of hydrophobic organic clay and hydrophilic natural clay, are arranged between the first polymer including the biodegradable polymer and the second polymer incompatible with the first polymer, the agent As the affinity between the first polymer and the second polymer is increased, morphology is controlled, and mechanical properties such as tensile elongation may be improved.
