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 Tg of plasticized EC films decreased from 122 to 71°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 Tg from 81 to 61°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 montmorillonite (MMT) into the EC films or the ring opening reaction of ESO plasticizer cause enhancement of mechanical properties.
