초록

고분자 재료의 사용이 늘어남에 따라 난연성 고분자 재료에 대한 연구가 더욱 활발히 진행되고 있다. 고분자 재료의 난연성 향상을 위한 방법으로 제조된 섬유의 후처리 또는 섬유내 난연제의 도입에 관한 연구가 진행되고 있다. 많은 고분자들 중 탄소섬유 전구체인 폴리아크릴로니트릴(PAN)은 의류용으로도 많이 사용되고 있어서 낮은 난연성을 지닌 PAN으로 이루어진 소재의 난연성 향상이 절실히 요구되고 있다. 본 총설 논문에서는 PAN 섬유의 후처리(안정화 또는 화학반응)을 통한 난연성 PAN 섬유와, 유/무기 소재(실리카, 2차원 소재, 탄소나노튜브)과 함께 혼합하여 섬유로 제조하는 난연성 PAN 복합소재의 제조에 대한 연구를 소개하고자 한다.

Development of flame retarding polymer based materials has been studied actively due to the increase in use of polymers. The post treatment of manufactured fibers or the introduction of flame retardant into fibers is representative method for the way to improve the flame retardancy. Among the polymers, polyacrylonitrile (PAN), which is a precursor of carbon fiber, has been widely used for clothes. Due to low flame retardancy of PAN fiber (LOI value: 17~18%), the improvement of flame retardancy of PAN fiber is needed. In this review paper, we report preparation methods for the fabrication of post-treated (oxidization or chemical reaction) flame-retarding PAN fibers and composites composed of PAN and organic/inorganic materials (SiO2, 2D materials or CNT).
