“…The agents modified the interface by interacting with filler and polymer, thus forming a link between the components [11] . It was reported that graft copolymers can be used effectively as compatibilizer for polymer blends [12] . This article reports an investigation on the tensile properties, morphology, and thermal properties of unmodified and modified eggshell powder filled LDPE composites.…”

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.

“…The density increased from 0.92 (for neat LDPE) to 1.25 g/cm 3 as 40 wt.% filler was incorporated. This increment can be attributed, first, to the large density of DPSP (consisting mainly of CaCO 3 ), which is nearly three times as large as that of the LDPE matrix [40]. In addition, the formation of crosslink structures also contributed to composite densification.…”

“…There was no declining trend in the tensile, yield, fracture and flexural strength even at 40 wt.% of filler level. Doufnoune et al [40] investigated the mechanical properties of LDPE composites filled with a coupling agentmodified nano-CaCO 3 and compatibilized with MAH-g-LDPE, at a filler content of 10 to 60 wt%. In their study, both the yield strength and the fracture strength increased continuously with the increase in filler content.…”

Filling and colorating are two important procedures in the polymer production. In this work, a bio-filler dye-loaded shell powder (DPSP) was prepared at first and then its filling and colorating effects on low density polyethylene (LDPE) polymer were investigated. SEM analysis showed the good dispersion of DPSP and strong interfacial adhesion. Mechanical property studies indicated that the incorporation of DPSP had an excellent filling effect at lower loading rate. Uniform color distribution in the specimens was also obtained at the premise of improving the mechanical performance of LDPE polymer. Vicat softening temperature tests indicated that the incorporation of DPSP could enhance the heat resistance of the composites. The optimal additive amount of DPSP was determined as 10 wt.% with a good balance between toughness and stiffness of LDPE composites.

“…The effect of surface modification of calcium carbonate on dispersions of thermoplastic polymer composites was tested in previous studies mostly by morphological and mechanical analysis. [3,4,[16][17][18][19] The study where the rheological behavior is measured for this purpose on the surface-modified CaCO 3 /PP composites is limited. [20,21] Since the screen pack analysis or filter test is usually applied in pigments, no study has been found by the authors including filter test demonstrating the effect of surface modification on dispersion of CaCO 3 in CaCO 3 /PP composites.…”

The excellent properties of the composites distinctly depend on the filler particles dispersion, which has close relationship with the surface treatment of filler particles. To improve the compatibility between the filler particles and the matrix, the surface of filler particles is generally treated with coating agents, which can be classified as “dispersants” and “coupling agents.” Coating calcite (CaCO3) with dispersants is called a nonreactive treatment. The surface modification of CaCO3 with coupling agents is called reactive treatment. In this study, physical, chemical, morphological, rheological, and mechanical analyses were conducted to determine the effect of reactive and nonreactive surface treatment agents on the dispersion of CaCO3 in polypropylene/CaCO3 composites. Both agents successfully made the surface of CaCO3 hydrophobic. The results of this study revealed that, although stearic acid (SA) establishes stronger bonds with the calcite surface, isopropyl tristearyl titanate, unlike SA, improves the properties of the final product composite, which forms a bond at the polymer/filler interface.
