Abstract
Polybutylene succinate (PBS) composites filled with various mass fractions of silicon carbide (SiC) particles were fabricated via slow melt extrusion. The morphological analysis revealed that the fabrication technique assisted in achieving a good adhesion between the PBS and SiC, along with excellent filler dispersion throughout the PBS matrix. The inclusion of 40 wt.% SiC in the PBS composite afforded a 10 °C increase in the thermal degradation temperature and a 160% enhancement in the thermal conductivity relative to the neat PBS. The crystallization temperature also increased with the inclusion of SiC particles, thus making the composites easier to process. Furthermore, the improvement in the Young’s modulus of the PBS composites increased their rigidity and stiffness relative to the neat PBS.
Highlights
For many years, plastic materials have been manufactured from polymers derived from petrochemical sources.Recently, strict governmental legislations have been implemented to prevent climate change due to the large-scale generation of harmful plastic wastes.many researchers are shifting towards fabricating environmentally friendly and biodegradable plastic products [1,2,3]
The results presented in Figure the temperature at which degradation begins, i.e., the degradation onset temperature (Tonset ), is lower
The commercial demand for biodegradable polymer-based plastic materials has significantly increased because of climate change and the excessive generation of wastes associated with the use of petrochemical-based polymer materials
Summary
Plastic materials have been manufactured from polymers derived from petrochemical sources. Many researches have fabricated filler-reinforced PBS to provide composite materials with enhanced thermomechanical properties. In previous work [19], the present research group has investigated the thermomechanical properties of an Al2 O3 -filled PBS composite fabricated via melt extrusion. These composites exhibited a superior thermal conductivity and storage modulus compared with the neat PBS. Silicon carbide (SiC) is a ceramic filler often used as a reinforcement in polymer composites owing to its outstanding strength, excellent hardness, and high thermal conductivity [20,21]. SiC-filled PBS composites were fabricated via melt extrusion at a low screw rotation speed designed to enhance the dispersion of the.
