| Abstrak/Abstract |
Antibacterial materials are increasingly significant, particularly for biomaterials and food packaging applications. Materials
with good elasticity and antibacterial properties are crucial in this line of work. This study focused on the investigation of
nanofiber properties in elasticity and antibacterial by combining Moringa oleifera (MO) zinc oxide nanoparticles (ZnO NPs)
with polyvinyl alcohol (PVA) nanofiber. The PVA/MO/ZnO nanofiber is fabricated using the electrospinning method. The
morphology of PVA/MO/ZnO nanofiber shows smooth and uniform fibers with 292 nm in diameter size. The EDX mapping
also demonstrates the successful loading of ZnO NPs into fibers, and the tensile test gives modulus Young as 290 MPa, which
corresponds to good elasticity or flexibility for biomedical applications. The antibacterial activity of PVA/MO/ZnO nanofiber
mats against gram-positive
and gram-negative
microbial species shows a good inhibition zone of 6.84 mm for Escherichia coli
bacteria. The hydrophilicity of the nanofibers also supported this antibacterial activity. These results show that PVA/MO/
ZnO nanofiber is certainly a potential material that has good elasticity and antibacterial properties, which may be useful in
biomaterial applications, food packaging, and coating material. It also suggested the simple preparation of an antibacterial
material with good elasticity. |
