Abstract

Penelitian modifikasi kain menjadi material antibakteri terus dilakukan seiring dengan meningkatnya kebutuhan masker. Kain katun (CF) banyak dipilih sebagai bahan masker karena fleksibel dan mudah menyerap air. Di sisi lain, material zeolitic imidazolate frameworks tipe 8 (ZIF-8) menunjukkan sifat antibakteri yang baik. Material ZIF-8 dan Kitosan/ZIF-8 (CS/ZIF-8) telah berhasil disintesis pada suhu ruang dalam pelarut asam asetat 2%, dengan penambahan kitosan sebesar 30%, 60% dan 120% terhadap berat ZIF-8. Pola difraktogram XRD serta spektra FTIR ZIF-8 dan CS/ZIF-8 sesuai dengan difraktogram dan spektra yang telah dilaporkan untuk material ZIF-8. Selain itu, ZIF-8 dan Kitosan/ZIF-8 telah berhasil dilapiskan pada kain katun secara langsung pada saat proses sintesis, dan berturut-turut dinotasikan sebagai ZIF-8@CF dan CS/ZIF-8@CF. Morfologi permukaan ZIF-8, CS/ZIF-8 dan ZIF-8@CF yang diamati dengan SEM-EDX menunjukkan bahwa ZIF-8 memiliki bentuk dodecahedron yang tetap teramati pada CS/ZIF-8 dan ZIF-8@CF. Hasil pengujian antibakteri menunjukkan bahwa ZIF-8, CS/ZIF-8 dan ZIF-8@CF memiliki aktivitas antibakteri yang baik terhadap Escherichia coli dan Staphylococcus aureus. ===================================================================================================== Research on modification of fabric into antibacterial materials is of great significance due to the increasing need for masks. Cotton fabrics are widely choosen due to their flexibility and water absorptivity. On the other hand, zeolitic imidazolate frameworks type 8 (ZIF-8) shows good antibacterial properties. The synthesis of ZIF-8 and Chitosan/ZIF-8 (CS/ZIF-8) had been successfully carried out at room temperature in 2% acetic acid solvent, with the addition of 30%, 60% and 120% chitosans by weight of ZIF-8. The XRD diffractogram patterns as well as the ZIF-8 and CS/ZIF-8 FTIR spectra were in accordance with the diffractograms and spectra that had been reported for the ZIF-8 material. In addition, ZIF-8 and Chitosan/ZIF-8 had been successfully coated on cotton fabrics directly during the synthesis process and were denoted as ZIF-8@CF and CS/ZIF-8@CF, respectively. The surface morphology of ZIF-8, CS/ZIF-8 and ZIF-8@CF equipped with SEM-EDX showed that ZIF-8 had a dodecahedron shape that was still visible in CS/ZIF-8 and ZIF-8@CF. The antibacterial test results showed that ZIF-8, CS/ZIF-8 and ZIF-8@CF had good antibacterial activity against Escherichia coli and Staphylococcus aureus.
