摘要

Invention Patent "IMPROVEMENT IN THE METHOD OF OBTENTION OF A SEMICONDUCTOR POLYMERIC COMPOUND BASED ON LAMPBLACK, OBTAINED IMPROVED SEMICONDUCTOR POLYMERIC COMPOUND BASED ON LAMPBLACK AND IMPROVEMENT IN THE METHOD FOR THE OBTENTION OF A POLYMERIC SEMICONDUCTOR BASED ON LAMPBLACK AND OBTAINED IMPROVED POLYMERIC SEMICONDUCTOR BASED ON LAMPBLACK" the first including essentially a formulation "A" phase using: (a) polymeric matrices; (b) conductive lampblack; (c) spreading agent; (d) anti-oxidant agent and (e) coupling agent; and a "B" phase consisting essentially in the incorporation of the conductive component in the polymeric matrix made through a spreading misture stage; the polymeric semiconductor compound based on lampblack consisting of: low density polyethilene (PEBD); acetate ethylene copolymer; conductive lampblack with selected porous structure; spreading agent consisting of Calcium Stearate; anti-oxidant, and Calcium Titanate coupling agent; the method for the obtention of the polymeric semiconductor based on lampblack consisting of: use of the polymeric semiconductor compound based on lampblack as described above, moulded through extrusion and calendering; and the improved polymeric semiconductor based on lampblack consisting of a body with suitable form and composed of: low density polyethilene (PEBD); acetate ethylene copolymer; lampblack; Calcium Stearate; anti-oxidant, and Calcium Titanate, extruded, calendered and with the lampblack aggregations having high degree of shearing and low degree of direction.
