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.

Abstract
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.
