Physico-Mechanical Analysis of Free Ethylcellulose Films Plasticized with Incremental Weight Percents of Dibutyl Sebacate

This research was conducted to investigate the physico-mechanical characteristicsof the ethylcellulose-based coating membranes plasticized with different weightpercents of dibutyl sebacate. in this experiment, free thin polymer sheetings of thesample formulations, by incorporating incremental weight percents of the plasticizer,were prepared employing a revised casting method of delayed solvent evaporation,whereby similar flat specimens of standard dimensions were subjected to tensileloadings and extensions. the data were analyzed to fairly decide on a moderateconcentration of the plasticizer to provide a rationale explanation of a strong, hard,and tough structure among the specimens. the data revealed that 40% (w/w) of theester results in the toughest structure amongst the similar specimens of the seriesleading to an ultimate toughness of 3.31 mj/m3.
