Abstract

In this study, ethyl cellulose (EC)/montmorilloniote(MMT) nanocomposite films plasticized with environmental-friendly plasticizer (BET, EBN, ESO) were prepared by melt process using Hakke mixer. The $T_g$ of plasticized EC films decreased from 122 to $71^{circ}C$ with the increase in the BET content up to 30 $wt\%$. The addition of 10 $wt\%$ epoxidized soybean oil (ESO) as the second plasticizer cause the further drop of $T_g$ from 81 to $61^{circ}C$. The plasticizer-effect of BET was better than that of EBN. When the plasticizer was added into the EC films, the mechanical properties of EC films was decreased, however the addition of monotmorillonite (MMT) into the EC films or the ring opening reaction of ESO plasticizer cause enhancement of mechanical properties.

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.
