Abstract
An electrically conductive composition and a method for producing same, for example by injection molding. The composition includes a matrix comprising substantially a first thermoplastic component, a second thermoplastic component having a higher polarity than that of the first thermoplastic component, the second component encapsulating a plurality of fibers forming a network of encapsulated fibers within the matrix, and a carbon component preferentially attracted to the second component so as to make said network an electrically conductive network within the matrix.
Claims36
An electrically conductive composition comprising:
- a matrix comprising substantially a first thermoplastic component;
- a second thermoplastic component having a higher polarity than that of said first thermoplastic component, said second component encapsulating a plurality of fibers forming a network of encapsulated fibers within said matrix;
- and
- a carbon component preferentially attracted to said second component so as to make said network an electrically conductive network within said matrix, said carbon component located at the interface between said second thermoplastic component and said matrix wherein said carbon component is carbon black and is present in an amount less than 10 parts per hundred.
A method for producing an electrically conductive composition comprising the step of compounding a matrix comprising substantially a first thermoplastic component with a second thermoplastic component having a higher polarity than that of said first thermoplastic component, said second component encapsulating a plurality of fibers forming a network of encapsulate fibers within said matrix;
- and
- a carbon component preferably attracted to said second component so as to make said network an electrically conductive network within said matrix, said carbon component located at the interface between said second thermoplastic component and said matrix wherein said carbon component is carbon black and is present in an amount less than 10 parts per hundred.
