Abstract

The invention belongs to the technical field of high molecular materials and specifically discloses a preparation method of a conductive polyether ether ketone composite material. After a large numberof comparative tests on a polyether ether ketone substrate, a conductive filler and an additive, an optimal formula is finally obtained; the prepared conductive composite material can be used for a long term under the condition of 250-300 DEG C and has a very good mechanical property; compared with an existing alkane-based and rubber-based material, the conductive polyether ether ketone compositematerial has higher mechanical property and is greatly improved in tensile, compression and impact resistance; the conductive polyether ether ketone composite material can be widely used in chemical,metallurgy, medicine and other industries, so that the application field of the high molecular composite material under high-temperature and severe conditions is expanded.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a preparation method of a conductive polyether ether ketone composite material. Background technique [0002] With the advancement of science and technology, polymer functional composite materials have received more and more attention from various fields because they have both the performance of polymers and the characteristics of fillers. With the rapid development of electronic information technology and aerospace, polymer matrix composites with conductive properties have attracted more attention. Polymer-based conductive composite materials generally add conductive polymers or fillers to the matrix polymer by physical or chemical means. On the one hand, it has the mechanical and thermal properties of high-quality polymers, and on the other hand, it also has considerable electrical conductivity. Classified according to the properties of polymer matrix ma...
