젖음성 및 전기저항 측정을 이용한 플라즈마 처리된 단일 탄소섬유 강화 탄소나노튜브-페놀수지 나노복합재료의 계면접착력 향상 = Improvement of Interfacial Adhesion of Plasma Treated Single Carbon Fiber Reinforced CNT-Phenolic Nanocomposites by Electrical Resistance Measurement and Wettability

다국어 초록 (Multilingual Abstract)

Optimal dispersion and fabrication conditions of carbon nanotube (CNT) embedded in phenolic resin were determined by electrical resistance measurement; and interfacial property was investigated between plasma treated carbon fiber and CNT-phenolic composites by electro-micromechanical techniques. Wettability of carbon fiber was improved significantly after plasma treatment. Surface energies of carbon fiber and CNT-phenolic nanocomposites were measured using Wilhelmy plate technique. Since surface activation of carbon fiber, the advancing contact angle decreased from 65° to 28° after plasma treatment. It was consistent with static contact angle results of carbon fiber. Work of adhesion between plasma treated carbon fiber and CNT-phenolic nanocomposites was higher than that without modification. The interfacial shear strength (IFSS)and apparent modulus also increased with plasma treatment of carbon fiber.
