Abstract

Bioactive glass is currently considered a material with a high biocompatibility and has been used both in the field of bone regeneration and in the preparation of cosmetic products with the controlled release of active compounds. The present work involved a study on the synthesis of bioglass using the sol-gel process. The study aims to evaluate the influence of the treatment of bioglass with Polyethylene glycol 4000 (PEG 4000) on its main characteristics. The surface characteristics of this material were obtained by nitrogen adsorption/desorption analysis, using the standard BET (Brunauer-Emmett-Teller) equation, the crystallinity by XRD (X-ray diffraction) analysis, the surface structure by SEM (Scanning Electron Microscope), thermal stability by TGA (ThermoGravimetric Analyses), and chemical bonds changes by FTIR (Fourier transform infrared) spectroscopy. After treatment with PEG 4000, the average diameter of the pores increased insignificantly, the crystallinity peak disappeared, and the SEM analysis highlighted several clusters of very small sizes.

PEG 4000 对 58S 生物活性玻璃的物理和微观结构特性的影响。

生物活性玻璃目前被认为是一种具有高度生物相容性的材料，已被用于骨再生领域和制备可控制活性化合物释放的化妆品。本研究涉及利用溶胶-凝胶工艺合成生物玻璃。研究旨在评估用聚乙二醇 4000（PEG 4000）处理生物玻璃对其主要特性的影响。利用标准 BET（布鲁瑙尔-艾美特-泰勒）方程，通过氮吸附/解吸分析获得了这种材料的表面特征；通过 XRD（X 射线衍射）分析获得了结晶度；通过 SEM（扫描电子显微镜）获得了表面结构；通过 TGA（热重分析）获得了热稳定性；通过 FTIR（傅立叶变换红外）光谱获得了化学键的变化。经 PEG 4000 处理后，孔隙的平均直径明显增大，结晶峰消失，扫描电镜分析显示出几个非常小的簇。

期刊介绍： Nanomaterials (ISSN 2076-4991) is an international and interdisciplinary scholarly open access journal. It publishes reviews, regular research papers, communications, and short notes that are relevant to any field of study that involves nanomaterials, with respect to their science and application. Thus, theoretical and experimental articles will be accepted, along with articles that deal with the synthesis and use of nanomaterials. Articles that synthesize information from multiple fields, and which place discoveries within a broader context, will be preferred. There is no restriction on the length of the papers. Our aim is to encourage scientists to publish their experimental and theoretical research in as much detail as possible. Full experimental or methodical details, or both, must be provided for research articles. Computed data or files regarding the full details of the experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material. Nanomaterials is dedicated to a high scientific standard. All manuscripts undergo a rigorous reviewing process and decisions are based on the recommendations of independent reviewers.
