| 초록 | Highly conductive and transparent poly(3,4-ethylenedioxythiophene) (PEDOT) thin two dimensional (2D) films and one dimensional (1D) micro patterned structure can effectively be prepared via vapor-phase polymerization (VPP) [1]. Moreover, several mechanically robust organic-inorganic hybrid conductive film have been reported using simultaneous co-vaporization VPP with conductive monomer and alkoxysilane precursor [2-4]. Three dimensional (3D) electric conducting porous structures should be a promising platform that could be utilized in emerging 3D structural electronics, energy storage systems, and biomedical applications [5]. A PEDOT-SiO2 composite with foam-like conducting open skeletal structures and pore sizes exceeding 100 nm is presented as shown in Fig. A two-step procedure was used to prepare this functional porous structure. First, a conformal coating layer was synthesized via VPP onto a randomly sized biodegradable microparticle assembly. VPP allowed for facile coating of the nanoscale layer in a relatively short processing time. At this stage, non-invasive chemical modification can be also accomplished on the surface of microparticles that have complex surface morphology. Secondly, biodegradable microparticles were selectively removed to form a high-porosity skeletal conducting structure. The composite demonstrated structural integrity despite an unusually high porosity of greater than 96%, which was confirmed through micro-computed tomography (CT). The results show that this foam-like conducting open skeletal structure of the PEDOT- SiO2 composite would be a good candidate for new applications. 참고문헌 1. J. S. Choi, K. Y. Cho, J.-H. Yim, Euro.
