Abstract

In the present study, biodegradable polyhydroxybutyrate-chitosan blends were prepared using an acoustic cavitation-assisted precipitation method. The effects of different ratios of polyhydroxybutyrate and chitosan on the thermal and morphological properties of the blends were investigated. Differential scanning calorimetry showed a shift in the melting point to 164 °C for the polyhydroxybutyrate–chitosan blend, compared to the initial melting point of 97 °C for chitosan. It was also observed that the crystallinity of the blends significantly increased due to the addition of polyhydroxybutyrate into chitosan. Fourier transform infrared spectroscopy and NMR studies confirmed the chemical interactions between polyhydroxybutyrate and chitosan. Scanning electron microscopy analysis illustrated noticeable changes in surface morphology of the polyhydroxybutyrate-chitosan blends compared to virgin polyhydroxybutyrate and chitosan individually. Adjusting the proportion of chitosan played a pivotal role in regulating the composite’s characteristics-an essential aspect for its potential biomedical applications in the future.

声空化辅助制备聚羟基丁酸酯-壳聚糖复合材料及表征

本研究采用声空化辅助沉淀法制备了可生物降解的聚羟基丁酸酯-壳聚糖共混物。考察了聚羟基丁酸酯与壳聚糖的不同配比对共混物热性能和形貌的影响。差示扫描量热法表明，与壳聚糖的初始熔点97℃相比，聚羟基丁酸酯-壳聚糖共混物的熔点转变为164℃。在壳聚糖中加入聚羟基丁酸酯，可显著提高共混物的结晶度。傅里叶变换红外光谱和核磁共振研究证实了聚羟基丁酸酯和壳聚糖之间的化学相互作用。扫描电镜分析表明，聚羟基丁酸盐-壳聚糖共混物的表面形貌与单独的聚羟基丁酸盐和壳聚糖相比有明显的变化。调整壳聚糖的比例对调节复合材料的特性起着关键作用，这是其未来潜在的生物医学应用的一个重要方面。图形抽象

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.
