MIXED MATRIX MEMBRANES USING HOLLOW ALUMINUM SILICATE NANOPARTICLES

摘要

A polydimethylsiloxane(PDMS) mixed membrane containing porous aluminum silicate nanoparticles is provided to improve permeability and selectivity of the PDMS polymer membrane by adding porous aluminium silicate nanoparticles to a PDMS polymer membrane, thereby manufacturing the PDMS mixed membrane. In a polymer membrane comprising a porous nano-sized inorganic material, a polydimethylsiloxane(PDMS) mixed membrane containing porous aluminum silicate nanoparticles comprises PDMS as a polymer matrix and porous aluminum silicate nanoparticles as the porous nano-sized inorganic material. The polydimethylsiloxane(PDMS) mixed membrane comprises 0.1 to 10 weight parts of the porous aluminum silicate nanoparticles based on 100 weight parts of the PDMS. The porous aluminum silicate nanoparticles are modified with a surfactant. The surfactant is undecylenic acid. The PDMS has a vinyl group or an acetic acid group as a functional group on an end group thereof.
