Polymer Synergy: Enhancing PA6/PLA Properties with POE-g-MA and Bioactive Glass for Advanced Biomedical Solutions
This study examined the effects of adding Polyethylene-octene elastomer modified with maleic anhydride (POE-g-MA) as a compatibilizing agent, along with bioactive glass particles (BG), to a blend of polyamide 6 (PA6) and poly (lactic acid) (PLA). The research focused on analyzing the morphology, rheological behavior, thermomechanical characteristics and shape memory capabilities of the resulting composite materials. Utilizing Field Emission Scanning Electron Microscopy (FE-SEM) and Transmission Electron Microscopy (TEM), it was found that the inclusion of the compatibilizer and BG significantly improved dispersion and phase interactions within the matrix, which was linked to enhanced interfacial adhesion. The addition of BG also contributed to greater thermal stability, as indicated by a rise in the activation energy (Ea) required for thermal degradation of the samples. Contact angle and degradation analysis indicate good biocompatibility and biostability of composites. Mechanical tests demonstrated notable improvements in Charpy impact strength and tensile strength for the “P80/L20/C5/BG10” sample, showing increases of over 120% and 56%, respectively, compared to the PA6/PLA blend without additives. Rheological studies revealed that the inclusion of both the compatibilizer and BG modified the viscoelastic characteristics of the samples, with zero shear rate viscosity and relaxation time increasing as BG content rose, in line with the Carreau-Yasuda model. Additionally, the combined effects of the compatibilizer and BG significantly enhanced the polymer’s ability to retain its shape, resulting in enhanced recovery factor (Rf) and recovery rate (Rr). This research highlights the potential of using POE-g-MA and BG to improve the performance attributes of PA6/PLA composites for advanced applications, demonstrating significant improvements in morphology, thermal stability, mechanical strength, rheological behavior, shape memory capabilities, and biomedical uses.
期刊介绍：
The Journal of Polymers and the Environment fills the need for an international forum in this diverse and rapidly expanding field. The journal serves a crucial role for the publication of information from a wide range of disciplines and is a central outlet for the publication of high-quality peer-reviewed original papers, review articles and short communications. The journal is intentionally interdisciplinary in regard to contributions and covers the following subjects - polymers, environmentally degradable polymers, and degradation pathways: biological, photochemical, oxidative and hydrolytic; new environmental materials: derived by chemical and biosynthetic routes; environmental blends and composites; developments in processing and reactive processing of environmental polymers; characterization of environmental materials: mechanical, physical, thermal, rheological, morphological, and others; recyclable polymers and plastics recycling environmental testing: in-laboratory simulations, outdoor exposures, and standardization of methodologies; environmental fate: end products and intermediates of biodegradation; microbiology and enzymology of polymer biodegradation; solid-waste management and public legislation specific to environmental polymers; and other related topics.
