Abstract

The objective of this research is to study antibacterial and hidrophobicity properties of nylon 6, 6 which coated nanoparticles - silver and hexadecyltrimetoxcysilane (HDTMS). The nanoparticle - silver was prepared with chemical reduction method by using tri-sodium citrate as reducing agent and PVA as stabilizer. Nanoparticle - silver is deposited on fabrics of nylon 6, 6 as antibacterial agent and HDTMS is coated on those as hydrophobic agent. The fabrics of nylon 6, 6 are characterized by analyzing the functional groups using ATR-FTIR, hydrophobic properties by measuring contact angle, and antibacteria properties by measuring clear zone. The addition of HDTMS compound can decrease intensity of absorption bands of functional groups but increase hydrophobicity property of nylon 6, 6. Nylon 6, 6 which coated nanoparticle silver and HDTMS has the highest antibacterial properties. The antibacterial properties of nylon 6, 6 before and after modification against Staphylococcus aureus ATCC 25923 and Eschericia coli 32518 are different. All samples have demonstrated a clear zone in inhibiting of growing bacteria Staphylococcus aureus ATCC 25923 and Escherichia coli ATCC 35218 at all the incubation time.
