초록

전도성 고분자 복합체 PEDOT:PSS에 실란 전구체인 TEOS 또는 GOPS를 혼합하여 고분자 에어로젤을 제작하고, 전자선 조사 공정에 따른 비저항과 스트레스-스트레인 특성을 연구하였다. PEDOT:PSS/실란 에어로젤은 혼합수분산액의 균질화와 동결 건조를 통해 제작하였으며, 복합체 에어로젤에 대한 전자선 조사선량은 1에서 50 kGy까지 달리하였다. 용매 증기 처리를 통해 전도도를 향상시킨 에어로젤의 저항은 전자선 조사에 따라 증가하였다. PEDOT:PSS/TEOS 에어로젤은 전자선 조사에 따라 경직성이 증가하는 경향을 보였으나, PEDOT:PSS/GOPS 샘플은 경직도가 1~5 kGy에서 최대를 보였다. 이러한 경향 차이는 전자선 조사에 의한 공유결합 절단과 가교 기작의 경쟁에 따른 것으로 보인다.

We prepared polymer aerogels based on a conducting polymer, poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS), and silane precursors, such as tetraethylorthosilicate (TEOS) and (3-glycidyloxypropyl)trimethoxysilane (GOPS), and investigated their specific resistance and stress.strain behaviors as a function of electronbeam dose. PEDOT:PSS/silane aerogels were easily made by homogenizing and freeze-drying from the aqueous mixtures. The composite aerogels were irradiated by the high-energy electron beams with a dose ranging from 1 to 50 kGy. Solvent vapor treatment was also used to see the effects of irradiation on the properties of the resulting aerogels. The resistance of high-conductivity aerogels increased when irradiated. PEDOT:PSS/TEOS aerogels became stiffer when irradiated, whereas PEDOT:PSS/GOPS samples peaked the stiffness at 1~5 kGy. Different behaviors were likely from two competitive mechanisms of chemical scission and cross-linking caused by electron beams.
