Abstract
Biodegradable polymers and their composites are considered promising materials for replacing conventional polymer plastics in various engineering fields. In this study, poly(butylene succinate) (PBS) composites filled with 5% aluminum nitride nanoparticles were successfully fabricated. The aluminum nitride nanoparticles were surface-modified to improve their interaction with the PBS matrix. Field-emission scanning electron microscopy revealed that the nanocomposites with surface-modified nanoparticles had better interface interaction and dispersion in the polymer matrix than those with untreated nanoparticles. The PBS/modified AlN nanocomposites exhibited maximal thermal conductivity enhancement, 63.7%, compared to the neat PBS. In addition, other thermomechanical properties of the PBS nanocomposites were investigated in this study. The nanocomposites also showed a superior storage modulus compared to the neat PBS matrix. In this work, a PBS nanocomposite with suitable thermal conductivity that can be used in various electronic fields was fabricated.
Highlights
The development of petroleum-based plastic products has brought great benefits to people’s daily life [1]
We aimed to investigate the effects of incorporating a low faction of AlN on the physicomechanical properties of the poly(butylene succinate) (PBS)/AlN nanocomposite
Materials amounts of APTES and VTES (8–10 wt% based on the weight of AlN nanoparticles) were added to PBScontaining (Solpol 5000J)
Summary
The development of petroleum-based plastic products has brought great benefits to people’s daily life [1]. The large consumption of these plastics in the packaging, agricultural, and automobile industries has become a great concern for the environment [2]. Many industrial and academic studies have focused on the development and applications of eco-friendly materials that can replace non-degradable petroleum-based materials [1,2,3,4]. Composites, and blends have been the preeminent solution for fabricating eco-friendly materials. Biodegradable polymers include polylactic acid, polycaprolactone, poly(butylene succinate) (PBS), and poly hydroxyalkanoates. PBS is one of the most promising aliphatic polyesters, owing to its low cost, processability, biodegradability, and compostability [4,5]
