Low temperature preparation of nano TiO2 and its application as antibacterial agents
A low temperature preparation of nano TiO2 using sol-gel method was proposed.The antibacterial properties of the treatment solution and the treated cotton fabrics obtained via a dip-padding process were evaluated.XRD pattern shows that the nano TiO2 produced is an anatase phase.Aqueous nano-dispersion of the nano TiO2 exhibites positive results as an antibacterial finishing agent for cotton fabrics.The treatment solution possesses antibacterial rates of over 92％ and 88.9％ against Escherichia coli and Bacillus subtilis,respectively.The treated fabrics are slightly downgraded but still maintained over 89％ and 83％ of reduction towards the same bacteria.After washing for 50 times,the antibacterial performances of the treated fabric still remains at a relatively high level,indicating the durable characteristic of nano TiO2 treatment.
