Structures and Properties of Isotactic-Polypropylene/Synthesized Micro Cellulose Tray: Effects of Micro Cellulose Loading

Abstract:

Cellulose was derived from cotton fabric waste. Composites of microcellulose fibers (MC) and isotactic polypropylene (i-PP) was prepared by melting and mixing, and maleic anhydride grafted polypropylene (MA-g-PP) was used as compatibilizer. The MC was blended in different ratios up to 20 phr with i-PP using corotating twin-screw compounder and then a forming of trays was done by injection molding. Effects of MC on mechanical properties of i-PP were investigated. Changes in mechanical and morphological properties with different MC loading were discussed. The composite of i-PP/MA-g-PP/MC rendered better results in comparison with the i-PP/MC composite. The compressive strength and modulus of i-PP/MC composites increased with the addition of 20 phr MC. The i-PP/MA-g-PP/MC-20phr composites showed higher compressive strength and modulus than the i-PP/MC-20 phr without MA-g-PP due to increased interfacial interaction between MC and i-PP matrix. Thermal properties of i-PP/MC composites with and without MA-g-PP were not significantly different from pure i-PP. In conclusion, MC derived from cotton fabric waste could be used as a reinforcing agent for manufacturing thermoplastic.
