Abstract
Zinc oxide-1,2,3,4-butanetetracarboxylic acid (ZnO-BTCA) composite was synthesized by chemical method. It was coated by pad-dry-cure method on cotton fabric and characterized by FT-IR and SEM with EDX techniques. ZnO, ZnO-BTCA composite powder and ZnO-BTCA composite coated cotton fabric were tested for antibacterial activity against Gram positive (Staphylococcus aureus) and Gram negative bacteria (Escherichia coli) by agar well diffusion method. Antibacterial activity result reveals that inhibitory effect of ZnO-BTCA composite coated on cotton fabric against Escherichia coli was more potent than Staphylococcus aureus.
