摘要

The increasing demand of multifunctional fabric in medical textiles draws interest in nanotechnology-based surface treatments, with special focus on titanium dioxide (TiO2) nanoparticles (NPs). This research compares the functionality of conventional TiO2 and green-synthesized TiO2 NPs for cotton fabric functionalization while enhancing antibacterial activity, antioxidant activity, ultraviolet protection factor (UPF), self-cleaning properties, and cytotoxicity mitigation. Green synthesis used Aloe vera as a natural reducing agent, which is sustainable alternative to conventional chemical synthesis. Characterization of TiO2 NPs and treated fabrics was ensured by FT-IR, FE-SEM, EDX, and antibacterial activity test for functional groups, morphology, particle size, elemental composition, and antibacterial susceptibility analyses. FE-SEM results confirmed that the size of the TiO2 particles in conventional TiO2 was 118.64 nm, while for green-synthesized TiO2 NPs, it was 70.03 nm. Zone of inhibition (ZOI) was 9.2 mm for green-synthesized TiO2 NPs-treated fabric against E. coli and S. aureus, confirming antibacterial activity. The value of UPF was 42 for conventional TiO2 and 58 for green-synthesized TiO2 NPs-treated cotton fabric, confirming better UV protection offered by green-synthesized TiO2 NPs. TiO2 NPs-treated fabrics proved their better self-cleaning properties compared to conventional TiO2-treated fabrics. More importantly, the green-synthesized TiO2 NPs-treated cotton fabric proved low cytotoxicity compared to conventional TiO2-treated fabric, confirming their better biocompatibility. It was ensured that green-synthesized TiO2 NPs provide a more appropriate and secure alternative over conventional TiO2 for preparing multifunctional cotton fabric for medical textile applications.
