Summary
The modification of fibers 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 NPs (or molecules) to the fibers, resulting in the development of a novel composite or hybrid material. 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. Textile 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 response of the fiber/NPs composite was tested towards the degradation of model pollutants (dye) by UV-vis spectroscopy and the response to light exposure investigated by DRS analysis upon irradiation.
