▎ 摘  要

NOVELTY - Production of a translucent conductive polymer composite material involves mixing bromobutyl rubber and hexane to obtain a mixture (A), mixing a carbon-based filler and isopropyl alcohol, ultrasonically processing by adding a dimethyl silicone oil solution to obtain a mixture (B), adding and stirring mixture (A) to mixture (B) to obtain a mixture (C), hardening by injecting mixture (C), and uniformly forming several holes using a laser in a side-by-side or alternating arrangement to obtain a translucent conductive polymer composite material having a thickness of 0.5 mu m, a hole size of 0.5-2 mm, and a spacing between holes of 0.5-2 mm. After cutting the polymer composite material to a size of 150x 210 mm2 and attaching a conductive copper tape to both ends, a voltage of 20-58 V and a current of 0.34-0.91 A with direct current power supply are supplied, and when heat is generated at 10-50 W of power, the maximum heating temperature and heat uniformity are improved. USE - Production of translucent conductive polymer composite material. Uses include but are not limited to planar heating element in winter, windows of houses and automobiles, display component, and touch panel elements. ADVANTAGE - The method enables manufacture of semi-transparent conductive polymer composite material having excellent transparency, conductivity and heat-generating properties. DETAILED DESCRIPTION - Production of a translucent conductive polymer composite material involves mixing bromobutyl rubber and hexane to obtain a mixture (A), mixing a carbon-based filler and isopropyl alcohol, ultrasonically processing by adding a dimethyl silicone oil solution to obtain a mixture (B), adding and stirring mixture (A) to mixture (B) to obtain a mixture (C), hardening by injecting mixture (C) into a hot press, and uniformly forming several holes using a laser in a side-by-side arrangement or an alternating arrangement to obtain a translucent conductive polymer composite material having a thickness of 0.5 mu m, a hole size of 0.5-2 mm, and a spacing between the holes of 0.5-2 mm. After cutting the translucent conductive polymer composite material to a size of 150x 210 mm2 and attaching a conductive copper tape to both ends, a voltage of 20-58 V and a current of 0.34-0.91 A with direct current power supply are supplied, and when heat is generated at 10-50 W of power, the maximum heating temperature and heat uniformity are improved, and the heating rate and cooling rate are improved due to uniform transfer of heat by the uniform arrangement of the holes.
