Effect of Polyethylene-Grafted Maleic Anhydride (PE-g-MAH) on Properties of Low Density Polyethylene/Eggshell Powder (LDPE/ESP) Composites

Abstract

The effect of polyethylene-grafted maleic anhydride (PE-g-MAH) on the tensile properties, morphology and thermal properties of low-density polyethylene (LDPE)/eggshell powder (ESP) composites was studied. LDPE/ESP composites with different eggshell powder content and the addition of PE-g-MAH were prepared with Z-blade mixer at 180 C and rotor speed of 50 rpm. The tensile strength, elongation at break and thermal stability of LDPE/ESP composites with PE-g-MAH were greater than LDPE/ESP composites, and their differences became more pronounced at higher filler content. The interfacial adhesion between ESP and LDPE was improved with the addition of PE-g-MAH as evidenced by the morphological study.

Effects of (conductive polypyrrole)‐modified tire dust on the mechanical, electrical, and morphology properties of (low‐density polyethylene)/(tire dust) composites

“…These results indicate that higher filler loading increased the thermal stability of the composites. A similar observation was reported by other researchers because of the presence of a large content of inorganic materials in the composites.…”

Properties of Tyre Dust-Filled Low Density Polyethylene Composites: The Effect of Phthalic Anhydride

“…The main purpose of incorporation of particulate filler into polymer matrix is to improve the modulus of elasticity of the composites. Modulus of elasticity of the composites is strongly affected by the filler modulus, filler loading and filler aspect ratio [15] . Again similar to the tensile strength result, the LDPE=TD M composites with phthalic anhydride possess a higher modulus of elasticity than LDPE= TD composites.…”

Enhancing interfacial adhesion performance by using poly(vinyl alcohol) in (low‐density polyethylene)/(natural rubber)/(water hyacinth fiber) composites

“…Finally, premature failure of the composites occurred and caused a lower tensile strength with higher fiber content. As the fiber loading increased, the fibers tended to agglomerate because of the increased tendency for filler–filler interaction rather than filler–matrix interaction .…”
