Abstract

In this research study, we describe the synthesis of new and tailored bio-composite materials by leveraging the synergistic interaction between polycaprolactone (PCL) and carboxymethyl hydroxypropyl guar gum (CMHPG). The proposed approach involves the in-situ ring opening polymerization (ROP) of ε-caprolactone, enabling the grafting of high molecular weight PCL chains (100 kg.mol⁻¹) onto CMHPG using a highly stable tin-based catalyst. The successful covalent association between the hydrophobic PCL chains and the hydrophilic CMHPG polysaccharide was confirmed. In addition, comprehensive structural (FTIR, DLS, contact angle and DRX), thermal (TGA and DSC), and mechanical characterizations were performed to investigate the synergistic effects between PCL and CMHPG. Notably, by precisely controlling the amount of CMHPG filler incorporated during synthesis, we achieved tailored performance in terms of film hydrophobicity and controlled biodegradability kinetics. These findings underscore the significant potential of the developed PCL bio-composites for specialized applications such as coatings, surface engineering, and the production of antifouling or repellent materials.

聚己内酯（PCL）和瓜尔胶衍生物的协同作用造就了量身定制的可持续生物复合材料

在本研究中，我们介绍了利用聚己内酯（PCL）和羧甲基羟丙基瓜尔胶（CMHPG）之间的协同作用合成新型定制生物复合材料的方法。所提出的方法涉及ε-己内酯的原位开环聚合（ROP），利用高度稳定的锡基催化剂将高分子量 PCL 链（100 kg.mol-1）接枝到 CMHPG 上。疏水性 PCL 链与亲水性 CMHPG 多糖之间成功的共价结合得到了证实。此外，还进行了全面的结构（傅立叶变换红外光谱、DLS、接触角和 DRX）、热（TGA 和 DSC）和机械特性分析，以研究 PCL 和 CMHPG 之间的协同效应。值得注意的是，通过在合成过程中精确控制 CMHPG 填料的加入量，我们在薄膜疏水性和可控生物降解动力学方面实现了量身定制的性能。这些发现强调了所开发的 PCL 生物复合材料在涂料、表面工程、防污或驱避材料生产等专业应用领域的巨大潜力。

期刊介绍： Journal of Polymer Research provides a forum for the prompt publication of articles concerning the fundamental and applied research of polymers. Its great feature lies in the diversity of content which it encompasses, drawing together results from all aspects of polymer science and technology. As polymer research is rapidly growing around the globe, the aim of this journal is to establish itself as a significant information tool not only for the international polymer researchers in academia but also for those working in industry. The scope of the journal covers a wide range of the highly interdisciplinary field of polymer science and technology, including: polymer synthesis; polymer reactions; polymerization kinetics; polymer physics; morphology; structure-property relationships; polymer analysis and characterization; physical and mechanical properties; electrical and optical properties; polymer processing and rheology; application of polymers; supramolecular science of polymers; polymer composites.
