Rapid advancements in materials that offer the appropriate mechanical strength, barrier, and antimicrobial activity for food packaging are still confronted with significant challenges.In this study, a modest, environmentally friendly method was used to synthesize functionalized octakis(3-chloropropyl)octasilsesquioxane [fn-POSS] nanofiller.Composite films compared to the neat thermoplastic starch (TS) film, show improved thermal and mechanical properties.Tensile strength Power Bar results improved from 7.8 MPa to 28.
1 MPa (TS + 5.0 wt.% fn-POSS) with fn-POSS loading (neat TS).The barrier characteristics of TS/fn-POSS composites were increased by fn-POSS by offering penetrant molecules with a twisting pathway.Also, the rates of O2 and H2O transmission were decreased by 50.
0 cc/m2/day and 48.1 g/m2/day in TS/fn-POSS composites.Based on an examination of its antimicrobial activity, the fn-POSS blended TS (TSP-5.0) film exhibits a favorable zone of inhibition against the bacterial pathogenic Staphylococcus aureus Beaded Headstall and Escherichia coli.The TS/fn-POSS (TSP-5.
0) film lost 78.4% of its weight after 28 days in natural soil.New plastic materials used for packaging, especially food packaging, are typically not biodegradable, so the TS composite with 5.0 wt.% fn-POSS is therefore of definite interest.
The incorporation of fn-POSS with TS composites can improve their characteristics, boost the use of nanoparticles in food packaging, and promote studies on biodegradable composites.
