This study explores the synthesis, characterization, and potential applications of TiO-doped borate glasses and their glass-ceramics, focusing on their biological and electrical properties. Examining the impact of varying the TiO content on the structural, electrical, and antimicrobial properties of the prepared samples was done. X-ray diffraction, Fourier-transform infrared spectroscopy (FTIR), density, and Field emission scanning electron microscope (FESEM) were employed to analyze the material's structural integrity and phase transitions. The AC conductivity (σ) was measured within the frequency range of 0.042 kHz-1 MHz and at the temperature range of 298-573 (K). The estimated DC conductivity proved that incorporating of TiO at the expense of BaO results in higher conductivity values than those of the free glass and glass ceramic samples. The prepared samples exhibited a semiconducting nature. The dielectric constant (ɛ') values increase upon doping with TiO. The incorporation of TiO improved the bioactivity (antimicrobial) of the studied glasses, making it suitable for biomedical applications such as drug delivery and tissue engineering. Also, the long-term stability and cytotoxicity were evaluated. The results indicate that TiO-doped borate glasses and glass-ceramics present a promising avenue for the development of multifunctional materials that meet the demands of both biological and electrical applications.
本研究探索了TiO掺杂硼酸盐玻璃及其玻璃陶瓷的合成、表征和潜在应用,重点关注其生物学和电学性质。研究了改变TiO含量对所制备样品的结构、电学和抗菌性能的影响。采用X射线衍射、傅里叶变换红外光谱(FTIR)、密度和场发射扫描电子显微镜(FESEM)分析材料的结构完整性和相变。在0.042 kHz - 1 MHz的频率范围内以及298 - 573(K)的温度范围内测量交流电导率(σ)。估计的直流电导率证明,以牺牲BaO为代价掺入TiO会导致电导率值高于游离玻璃和玻璃陶瓷样品。所制备的样品表现出半导体性质。掺杂TiO后介电常数(ɛ')值增加。TiO的掺入改善了所研究玻璃的生物活性(抗菌性),使其适用于药物递送和组织工程等生物医学应用。此外,还评估了长期稳定性和细胞毒性。结果表明,TiO掺杂硼酸盐玻璃和玻璃陶瓷为开发满足生物学和电学应用需求的多功能材料提供了一条有前景的途径。
