Abstract

Particulate polymer composites have gained popularity because of their many uses. For some, using high loadings to achieve desired attributes without compromising the material’s mechanical properties or restricting its processability is desirable. It is possible to use surface active agents to improve characteristics and increase solid loading. Interface characteristics in highly packed particulate composites based on nano-calcite (nano-calcium carbonate) and polypropylene as a binder are the focus of the current study. Nano-calcite particles treated with pimelic acid were created by means of the surface modification technique. To create binary composites, four distinct amounts of nano-calcite were introduced to polypropylene. The mechanical property measurements revealed that the inclusion of fillers initially increased the composites’ elastic modulus and impact strength before decreasing them. At the same time, the tensile yield stress fell. Furthermore, pimelic acid was added to the composites, increasing their elastic modulus and impact strength. The pimelic acid treatment improved the interfacial adhesion between the filler and the matrix, according to the results of scanning electron microscopy. This suggests that the compatibility between the filler and matrix has improved, which is what caused the improvement in mechanical properties. Differential scanning calorimetry was used to examine the crystallization characteristics of virgin polypropylene and its composites. In contrast to virgin polypropylene and nano-composite, the results showed that adding pimelic acid-treated nano-fillers increased the crystallization temperature while simultaneously improving nucleation and crystallization.

Keywords: Nanocomposites, pimelic acid, mechanical properties, scanning electron microscopy (SEM), thermal properties
