An investigation on surface Morphology thermal stability Mechanical characterisation and In vitro studies of the natural Particulates filled biopolymer Composites

Abstract

In recent years, polymer composite have been widely used across different domains. Recently, hydroxyapatite [Ca10(PO4)6(OH)2] has been introduced as a bone graft material in medical applications due to its similar chemical composition of bone. In this research work, new biopolymer composites could be developed by using Fish Scale (FS) Catla (Labeo catla) and Seashell (SS) L. Canarium (Laevistrombus canarium) particulates filled different weight percentages in High-Density Polyethylene (HDPE) through compression and injection molding process. The presence of functional groups in the FS particulates and SS particulates was identified using Fourier Transform Infrared Spectroscopy (FTIR). The 29 value for the FS particulates, and SS particulates and corresponding to its crystalline plane orientation were analyzed through X-Ray Diffraction (XRD). newlineThe morphology of the FS particulates and SS particulates was examined using Field Emission Scanning Electron Microscope (FESEM). Also, the presence of elements was identified using Energy Dispersive X-Ray Analysis (EDX). The i) FS particulates, ii) SS particulates, and iii) combinations of FS particulates and SS particulates filled HDPE composite with different weight percentages (0, 10, 20, 30, 40, and 50 wt. %) was fabricated through the compression molding process. The prepared composite was tested to gauge the mechanical properties such as tensile strength, compressive strength, flexural strength, and Shore D hardness as per ASTM standards. The 30 wt. % i) FS particulates, ii) SS particulates, and iii) combinations of FS particulates and SS particulates filled HDPE newlineiv composite was carried out FTIR and XRD and confirmed the presence of functional groups and orientation of crystal plane. newline
