Summary
The modification of fibers and textiles has been widely explored towards the development of materials with specific and advantageous properties. This takes advantage from the possibility of imparting the properties of the modifying NPs (or molecules) to the fibers, resulting in the development of novel composite or hybrid materials. Successful examples are the attachment of Ag, TiO2 or BiOCl NPs to textile fibers for antibacterial, UV protection, self-cleaning and photocatalytic purposes, and the coating of fabrics with a hydrophobic layer (molecules or polymers) for water repellence and stain free fabrics. [1-4] \\nIn this work, several approaches for fibers modification are exploited towards the preparation of materials displaying photocatalytic and radiation sensing/protection responses, as illustrated in Figure 1. Several fibers, including cotton, polyester and carbon fibers, were in situ modified with semiconductor nanoparticles (e.g. BiOCl and TiO2). Their optical, structural and morphological properties were characterized by several techniques including XRD, DRS, FTIR, contact angle goniometry and SEM. The photocatalytic performance of the fiber/NPs composites was tested towards the degradation of dye pollutants and the response to light exposure investigated upon irradiation.
