GROWTH CONTROL OF ZnO-TiO2/CHITOSAN NANOROD ON COTTON TEXTILE FIBER BASED ON DIFFERENT CHLORO ACETIC MOLAR COMPOSITION AS CROSS LINKER

The objective of this research was to synthesize ZnO-TiO2/chitosan patterned nanorods with the molar composition of Zn and Ti at 3: 1 and pH of 13.0 using the Zinc Nitrate precursor as a source of ZnO and Titanium Iso Propoxide as doped TiO2. ZnO-TiO2/chitosan nanorods (Zn-Ti NRd) were later grown on textile cotton fibers by dip-spincoating technique through the optimization of the cross-linker function of Chloroacetic Acid (CAA) and NaOH base based on the differences in the molar composition, 3:1, 2:1, 1:1 and 1:2. The interaction of hydroxyl groups between the cellulose fibers CA carboxylic groups and Zn-TiNRd showed the intensity of C=O stretching at 1700 cm which was indicated as covalent ester interaction. With respect to the results of XRD characterization, Zn-Ti NRd crystals measuring 38.8 nm and SEM-EDX and TEM-SAED showed nanorod patterned particles. Moreover, photocatalytic activity showed an increase in the antibacterial properties of Zn-Ti NRd against Bacillus subtilis (ATCC 6633) with a zone of inhibition recorded as 23 mm after 24 hours of ultraviolet irradiation at 1:2 CAA and NaOH molar composition. An increase was observed in the mechanical properties of the fiber-based on the measured tensile strength of 25 cm with warp direction of 227 kg, feed direction at 154 kg and the tear strength by 0.64 kg and 0.56 kg respectively.
