To add Nanofiller in the epoxy which is used with the solid insulation material of existing and is a research which observes the improvement of the structural quality to produce the Nanocomposite. Montmorillonite uses with Nanofiller, MMT of the content expense (wt%) which is various and mixed an epoxide and produced sample. According to content of the sample result MMT according to respectively content expense to measure SEM photographing which is the possibility of knowing the minute structure of section with sample where is produced and the tensile strength will be able to observe the change of quality. MMT silicate layer uniformly more in the result and within epoxy matrix, being dispersed, will be able to observe.

본 연구에서는 친환경 가소제(BET, EBN, ESO)를 첨가한 에틸 셀룰로오스 필름과 몬모릴로나이트(MMT) 나노입자를 이용한 생분해성 나노복합재료를 Hakke mixer를 이용하여 용융가공 공정으로 제조하였다. 제조한 에틸 셀룰로오스 필름의 유리전이온도는 BET의 함량을 30 $wt\%$까지 증가시켰을 때 $122^{circ}C$에서 $71^{circ}C$로 감소하는 결과를 보였다. 여기에 2차 가소제로 에폭시화된 콩기름을 10$wt\%$ 함량으로 첨가할 경우에 유리전이온도가 $81^{circ}C$에서 $61^{circ}C$로 감소하였다. 가소효과는 EBN보다 BET가 더 효과적이었다. 에틸 셀룰로오스 필름에 가소제를 첨가할수록 기계적인 물성은 감소하였으나, 몬모릴로나이트의 첨가와 ESO가소제의 에폭시 개환중합을 통하여 기계적 물성을 증가시킬 수 있었다.

In this wort, the $Na^+-MMT$ has organically modified with silane intercalant to prepare the polymer/clay nanocomposites. The pH. X-ray diffraction (XRD), and contact angles were used to analyze the surface properties of clay and the exfoliation phenomenon of clay interlayer, The mechanical interfacial properties of epoxy/clay nanocomposites were investigated by three-point bending test. From the experimental results. the surface modification made by silane intercalant on clay surface leads to an increase of distance of silicate layers, surface acid value. and electron acceptor parameter of organoclay. The treatments are also necessary and useful for epoxy to intercalate into the interlayer by interacting of electron donor-accepter between basic epoxy and clay surface. The mechanical interfacial properties of the nanocomposites was improved by the presence of dispersed clay nanolayer containing low content of organoclay in comparison with the conventional, which increase the interfacial adhesion between dispersed clay and epoxy resins.
