| Abstract | Ethyl cellulose films plasticized with 0, 10 and 20% of five different plasticizers were prepared. The films were cast into teflon molds from ethanol solution. The plasticizers used were: dibutyl sebacate, triethyl citrate, triacetin, Myvacet(R) (acetylated monoglycerides) and diethyl phthalate. The physical properties of the films were evaluated using thermal analysis, tensile testing, porosimetry, scanning electron microscopy and hot stage microscopy. The results reported are glass transition temperature, tensile stress, percentage elongation at break, elastic modulus, total volume of pores, total surface area of pores and mean and median diameters of pores. On the basis of tensile tests and thermal analysis, dibutyl sebacate and Myvacet(R) were found to be the two most efficient plasticizers for ethyl cellulose films cast from ethanol solution. |
