LIGNIN POLYMER NANO-MATRIX COMPOSITE AND PREPARATION METHOD THEREFOR

摘要

The present invention relates to a lignin polymer nano-matrix composite and a preparation method therefor. The nano-matrix composite according to the present invention is characterized by comprising a lignin polymer and clay minerals. The lignin polymer nano-matrix composite according to the present invention can be prepared by melt-mixing lignin/clay-mineral composite particles with a lignin polymer or reacting lignin/clay-mineral composite particles with a lactone-based compound, and is melt-mixed with a second polymer, etc. to thereby show superior mechanical properties and thermal characteristics.
