چکیده
Abstract Development of bio-based polymers can reduce human dependence on fossil fuel and move to a sustainable material resource. In this work, thermoplastics starch (TPS) films were produced by plasticization process, in which the crystalline structure granules was destroyed reformed water glycerine through mechanical stirring heating process. Hectorite employed as filler reinforce TPS films. The hectorite subjected ultrasonication process for reducing size aggregation particles. ultrasonicated added into solution produce TPS/hectorite bio-composite film casting method. with loading range 1% 5% prepared. morphology, tear strength soil biodegradability studied altering incorporated Results showed that have higher compared pure slightly increased content 2%. However, 3%, there drastic increase strength. maximum value achieved when 4% employed. TPS/4% (ultrasonicated) has lowest rate biodegradation due its lower moisture uptake greatest interface interaction between hectorite, inhibiting diffusion bacteria
