Abstract

Chitosan and pectin form biocompatible polyelectrolyte complex hydrogels. This study investigates the impact of cellulose nanowhiskers (CNW) and NaCl on hydrogel’s properties, particularly in mechanical behavior. Swelling tests revealed deswelling under physiological conditions. Thermal analysis indicated enhanced crosslinking with CNW, correlating with mechanical, rheological, and nanoindentation findings. Hydrogels with 10% CNW exhibited higher elastic modulus in compression tests. Rheological studies showed comparable values to skin, promising for wound dressing applications. Nanoindentation highlighted CNWs' surface effect on adhesive modulus. Degradation tests over 21 days demonstrated higher degradation in NaCl-containing hydrogels. Overall, NaCl influenced polymer matrix interactions, while CNW incorporation enhanced hydrogel performance. This study distinguishes between surface and bulk properties of hydrogels, underscoring the potential of CNW in biomaterial applications.

壳聚糖/果胶/NaCl复合纤维素纳米晶须水凝胶的力学、流变性、纳米压痕和可降解性评价

壳聚糖和果胶形成生物相容性多电解质复合水凝胶。本研究探讨了纤维素纳米晶须（CNW）和NaCl对水凝胶性能的影响，特别是在力学行为方面的影响。肿胀试验显示在生理条件下出现肿胀。热分析表明与CNW的交联增强，与力学、流变学和纳米压痕研究结果相关。含有10% CNW的水凝胶在压缩试验中表现出更高的弹性模量。流变学研究显示了与皮肤相当的价值，有望用于伤口敷料应用。纳米压痕突出了CNWs表面对粘接模量的影响。21天的降解试验表明，含nacl水凝胶的降解率更高。总的来说，NaCl影响了聚合物基质的相互作用，而CNW的加入增强了水凝胶的性能。这项研究区分了水凝胶的表面和体积性质，强调了CNW在生物材料应用中的潜力。

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.
