Abstract

This study aimed to evaluate the effect of incorporating nanocrystalline cellulose (NCC) sourced from rice husk on the mechanical properties of a commercial glass ionomer cement (GIC). NCC was isolated through acid hydrolysis, and its crystallinity, chemical structure, and morphology were characterized through x-ray diffractometry, Fourier-transform infrared spectroscopy, and transmission electron microscopy, respectively. Various concentrations of NCC (0%, 0.5%, 1%, and 1.5%) were added to reinforce the GIC matrix. Mechanical tests including compressive strength, flexural strength, hardness, and shear bond strength were conducted on the modified GIC samples. The addition of NCC resulted in increased hardness and shear bond strength values, with 1% NCC showing the highest values compared to other concentrations. However, there was no significant improvement observed in the compressive and flexural strength of the modified GIC. Failure mode test revealed a reduction in adhesive failure with the addition of NCC. Incorporating small amounts of NCC (0.5%–1%) suggests a promising and affordable modification of GIC restorative material using biomass residue, resulting in improved mechanical properties.

用稻壳纳米纤维素改善玻璃离子聚合物水泥的力学性能

本研究旨在评估掺入从稻壳中提取的纳米结晶纤维素（NCC）对商用玻璃离子水泥（GIC）机械性能的影响。通过酸水解分离出 NCC，并分别通过 X 射线衍射仪、傅立叶变换红外光谱仪和透射电子显微镜对其结晶度、化学结构和形态进行了表征。为增强 GIC 基体，添加了不同浓度的 NCC（0%、0.5%、1% 和 1.5%）。对改性 GIC 样品进行了力学测试，包括抗压强度、抗弯强度、硬度和剪切粘结强度。添加 NCC 后，硬度和剪切粘接强度值均有所提高，与其他浓度相比，1% NCC 的硬度和剪切粘接强度值最高。不过，改性 GIC 的抗压和抗折强度没有明显提高。失效模式测试表明，添加 NCC 后粘合剂失效的情况有所减少。加入少量的 NCC（0.5%-1%）可以利用生物质残渣对 GIC 修复材料进行改性，从而改善其机械性能。

期刊介绍： Journal of Biomedical Materials Research – Part B: Applied Biomaterials is a highly interdisciplinary peer-reviewed journal serving the needs of biomaterials professionals who design, develop, produce and apply biomaterials and medical devices. It has the common focus of biomaterials applied to the human body and covers all disciplines where medical devices are used. Papers are published on biomaterials related to medical device development and manufacture, degradation in the body, nano- and biomimetic- biomaterials interactions, mechanics of biomaterials, implant retrieval and analysis, tissue-biomaterial surface interactions, wound healing, infection, drug delivery, standards and regulation of devices, animal and pre-clinical studies of biomaterials and medical devices, and tissue-biopolymer-material combination products. Manuscripts are published in one of six formats: • original research reports • short research and development reports • scientific reviews • current concepts articles • special reports • editorials Journal of Biomedical Materials Research – Part B: Applied Biomaterials is an official journal of the Society for Biomaterials, Japanese Society for Biomaterials, the Australasian Society for Biomaterials, and the Korean Society for Biomaterials. Manuscripts from all countries are invited but must be in English. Authors are not required to be members of the affiliated Societies, but members of these societies are encouraged to submit their work to the journal for consideration.
