摘要

海藻酸钠（SA）和二氧化钛（TiO2）纳米颗粒的纳米复合材料在过去十年中因其在多种应用中的广泛用途而备受关注。事实上，TiO2 因其光催化和抗菌活性以及固有的安全性而特别具有吸引力。本文采用简单的溶剂浇铸法，成功地将微波辅助法合成的 TiO2 纳米粒子嵌入到 SA 基质中，形成柔性自洽的 SA/TiO2 薄膜。傅立叶变换红外光谱（FT-IR）、X射线衍射（XRD）和接触角测量证实了均匀的亲水性生物复合薄膜的形成，这种薄膜可能适用于包装或生命科学应用。

Facile and Effective Method for the Preparation of Sodium Alginate/TiO2 Bio-Composite Films for Different Applications

Nanocomposites of sodium alginate (SA) and TiO₂ nanoparticles have gained attention in the last decade for their versatile uses in several applications. Indeed, TiO₂ is particularly appealing for its photocatalytic and antimicrobial activity and inherent safety. In this paper, TiO₂ nanoparticles are successfully embedded, synthesized by a microwave-assisted method, into SA matrix by a simple solvent casting method to form flexible and self-consistent SA/TiO₂ films. FT-IR, XRD, and contact angle measurements confirm the formation of homogeneous and hydrophilic bio-composites films that may be suitable for packaging or life science applications.
