- W3195969912 abstract "Improving leather quality with antifungal, antibacterial, and superior mechanical properties is an ongoing effort. The objectives of this research were to synthesize silver nanoparticle using Cyperus kyllinga extract as a bio-agent and to deposit synthesized silver nanoparticle into goat leather by ex situ and in situ, and also to characterize the properties of antibacterial, antifungal, mechanical, and contact angle of goat leather before and after modification. Preparation of silver nanoparticles by reduction method by adding Cyperus kyllinga’s leaf extract. The silver nanoparticle was characterized by using spectrophotometer UltraViolet-Visible and Particle Size Analyzer. The addition of Methyltrimethoxysilane (MTMS) compound on the leather sample to know hydrophobicity properties of the leather. The leather was modified by adding silver nanoparticle and silane compounds. The antibacterial and antifungal test was conducted by the diffusion method and tested the significance by using statistical analysis. The mechanical properties were tested through tensile strength test, elongation, and also modulus Young by using a tensile tester. The modified goat leather surface was tested the contact angle by using the sessile drop method. The characterization results indicated that silver nanoparticles were formed at a wavelength of 406.60 nm, with their particle size were 200.1 nm. The results of the antimicrobial test showed that modified goat leather using two methods of preparation had a different significance to inhibit the S. epidermidis and E. coli, and also fungi of C. albicans. The leather, after modification with nanoparticle via in situ method, had the highest antibacterial activities against S. epidermidis and E. coli. However, leather after modification with adding nanoparticle and MTMS via ex situ method has the highest antifungal activity against C. albicans. The leather after modification nanoparticle and MTMS via in situ method has the highest tensile strength and the largest toughness. All modified leathers had larger antimicrobial activity, contact angle, and also toughness compared to unmodified leather." @default.
