Preparation and application of semiconductor–polymer composites



Copper sulfide–polymer composite was prepared by depositing copper into porous polyolefine film with a method of electroless plating and sulfurizing the copper. The composite was an n-type semiconductor and useful as a component of p–n junction device and as a gas detector. The method was also useful for the preparation of silver sulfide–, nickel sulfide–, and cobalt sulfide–polymer composites.
