Effect of Poly(methyl Methacrylate) (PMMA) on Tensile Properties and Spectroscopy Infrared (FTIR) Characteristics of LDPE/WHF Composites

摘要

In this work, the effect of PMMA in low density polyethylene/water hyacinth fibers composites were prepared and characterized in terms of tensile properties and FTIR characteristics. Water hyacinth fibers (WHF) were incorporated into the LDPE matrix with different fiber loading. LDPE/WHF and LDPE/WHF_(PMMA) composites were prepared with Z-blade mixer at 180°C with rotor speed of 50 rpm. The PMMA modified WHF increased the tensile strength and Young's modulus while reduced the elongation at break of LDPE/WHF_(PMMA) composites in comparison with LDPE/WHF composites. The absorption peak at 1736.28 cm~(-1) indicated the presence of ester carbonyl group (C=O) in LDPE/WHF_(PMMA) composites.
