Title: METHOD FOR PRODUCING HIGH-PERFORMANCE NANOCOMPOSITE
Abstract:
[Problem] Providing a polyolefin material in which the inorganic filler in nano size is uniformly dispersed at a high concentration. [Solution] A method for producing a high-performance nanocomposite containing a polyolefin and a metal oxide comprising the following Steps 1-4: (Step 1 ) a step of impregnating a metal alkoxide which is a precursor of the metal oxide to a polyolefin powder; (Step 2) a step of removing a solvent by drying the polyolefin powder obtained in Step 1; (Step 3) a step of heating the polyolefin powder obtained in Step 2 under a water vapor atmosphere; and (Step 4) a step of melting and kneading the polyolefin powder obtained in Step 3, wherein the sol-gel reaction from the metal alkoxide as the precursor to the fine particles of the metal oxide is completed.
