摘要:
The present invention provides compositions comprising a graphite, binder precursor and low polarity solvent that upon hardening form layers of an electrically conductive material. The compositions of the present invention are sprayable by an internally charged electrostatic sprayer.
摘要:
A polymeric pigment dispersant of a graft polymer having an acrylic polymer backbone and pending from the backbone, polyester side chains, cyclic imide groups and quaternary ammonium groups and the polymer having a calculated number average molecular weight of 8,000-50,000; wherein the graft copolymer is composed of(a) 10-50%, by weight of the of the graft polymer, of an acrylic copolymer backbone having a number average molecular weight of 2500-10,000 which, before reaction, contains 25-75% by weight of polymerized oxirane containing monomers;(b) 20-85%, by weight of the graft polymer, of a polyester copolymer, or mixture of different polyester copolymers, having a number average molecular weight of 500-10,000 which polyester copolymer is carboxylic-acid functional and is attached to the backbone by a reaction of the carboxylic acid functional group with oxirane group of the backbone;(c) 1-16%, by weight of the graft polymer, of cyclic imide groups attached to the backbone by a reaction of the imide group with the oxirane group of the backbone and(d) 0.2-17%, by weight of the graft polymer, of quaternary ammonium groups.
