Eco-Friendly Manufacturing of Nano-TiO ₂ Coated Cotton Textile with Multifunctional Properties

摘要

In this work, multifunctional cotton fabrics were developed by immobilizing TiO_(2)nanoparticles (TiO_(2)-NPs) using an eco-friendly bath through a highly-scalable technique. The effects of TiO_(2)-NPs, cross-linking agent, catalyst and curing temperatures were assessed by analysis of variance and surface response methodology. The results disclose an excellent performance of treated textiles for various applications: flame-retardant (char content enhanced by 1000 %), photocatalytic decontamination (>90 % of contaminant abatement and feasibility for multiple reuses), self-cleaning of intense stains (up to 80 % of stain vanishing), bacterial inhibition without TiO_(2)UV-activation (≈25 % of bacteria growth reduction). Moreover, those properties were durable for at least five domestic laundering cycles.
