ELECTRICALLY CONDUCTIVE POLYMER COMPOSITE COMPOSITIONS METHOD FOR MAKING , AND METHOD FOR ELECTRICAL CONDUCTIVITY ENHANCEMENT.

摘要

INCLUSION OF RELATIVELY SMALL AMOUNTS OF ORGANIC IONIC SPECIES, SUCH AS CALCIUM STEARATE, IN THE PREPARATION OF AN ELECTRICALLY CONDUCTIVE POLYMER COMPOSITE COMPOSITION PROVIDES A COMPOSITION HAVING ENHANCED ELECTRICAL PROPERTIES RELATIVE TO THE COMPOSITE COMPOSITION LACKING THE ADDED ORGANIC IONIC SPECIES. AS A RESULT OF THIS ENHANCEMENT, NORMALLY INSULATING MATERIALS WHICH RELY UPON A CONDUCTIVE FILLER TO RENDER THEM ELECTRICALLY CONDUCTIVE, CAN BE MADE TO ACHIEVE A GIVEN LEVEL OF CONDUCTIVITY USING LESS OF THE CONDUCTIVE FILLER THAN WOULD OTHERWISE BE REQUIRED. AS A RELULT, THE ADVERSE EFFECTS OF THE CONDUCTIVE FILLER ON THE POLYMER'S PHYSICAL PROPERTIES CAN BE MINIMIZED WHILE MAINTAINING A HIGH LEVEL OF ELECSTRICAL CONDUCTIVITY.
