Studying the effect of nHAP on the mechanical and surface properties of PBS matrix

In this paper, we present a simple route to synthesize PBS/nHAP polymer nanocomposites and share our findings on the influence of nHAP (filler) on the PBS (matrix). The filler weight content was varied from 0.0 g to 0.10 g. These effects that were investigated were the structural, morphological, mechanical, wettability, and roughness parameters. The X-ray Diffraction (XRD) spectra revealed that PBS and nHAP produced their separate phases. The Scanning Electron Microscopy (SEM) results display pores in the Neat PBS while pores are filled in the PBS/nHAP polymer nanocomposites. Further increase in the filler content revealed that agglomeration began to occur, and it permeated out of the pores and onto the surface imparting brittleness to the composite. The mechanical results confirm the increase in tensile strength up to a certain point of nHAP-5. The wettability studies prove that by increasing the filler weight content, the hydrophobic nature converts to a moderate hydrophilic nature. The roughness studies revealed the roughness values of the PBS/nHAP composites to be higher than that of Neat PBS.

Automated summary

The research explores the impact of nHAP (filler) on PBS (matrix) by varying filler weight content. The XRD spectra show separate phases of PBS and nHAP, while SEM results indicate filled pores in PBS/nHAP composites. Mechanical testing reveals increased strength up to a certain point, and wettability studies demonstrate a shift towards moderate hydrophilicity with increasing filler content. Roughness values of PBS/nHAP composites are higher than Neat PBS.
