Embodiment 1

[0089] 95% by weight of PPS and 5% by weight of PSS-1 as a binder resin were mixed to prepare a conductive polyarylene sulfide resin composition. The prepared composition was injected into a high-temperature pressurized device as a composition for forming a conductive polymer film, and kept at 300° C. and 7 MPa for 1 minute to form a film (film thickness 0.14 mm). The weight-average molecular weight of PSS-1 used in the film was 70,000 g / mol, and no cracking occurred during film production.

Embodiment 2 to 5

[0091] Conductive polyarylene sulfide resin composition and conductive polymer film were prepared in the same manner as in Example 1, except that the amount of PSS-1 in the mixture of PPS and PSS-1 in Example 1 was changed to 10% by weight, 20% by weight, 30% by weight and 40% by weight (film thickness: 0.14mm). The weight-average molecular weight of PSS-1 used in the film was 70,000 g / mol, and no cracking occurred during film production.

Embodiment 6

[0093] 95% by weight of PPS and 5% by weight of PSS-2 as a binder resin were mixed to prepare a conductive polyarylene sulfide resin composition. The prepared composition was injected into a high-temperature pressurized device as a composition for forming a conductive polymer film, and kept at 300° C. and 7 MPa for 1 minute to form a film (film thickness 0.14 mm). The weight-average molecular weight of PSS-2 used in the film was 35,000 g / mol, and no cracking occurred during film production.

Abstract

The present invention provides a polyarylene sulfide resin composition having excellent electrical conductivity and high temperature stability.

Description

technical field [0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2017-0142610 filed with the Korean Intellectual Property Office on October 30, 2017, the entire contents of which are incorporated herein by reference. [0003] The present invention relates to a conductive polyarylene sulfide resin composition having excellent conductivity and high-temperature stability and particularly suitable for producing conductive polymer films. Background technique [0004] Polyarylenesulfide (PAS), represented by polyphenylene sulfide (PPS), is widely used in vehicles, electrical and electronic products, Alternatives to metals, especially die-cast metals such as aluminum or zinc, in machinery and the like. In particular, PPS resin has good fluidity, which is advantageous for use as a compound by kneading with a filler such as glass fiber, etc. or a reinforcing agent. [0005] Generally, PPS p...
