Abstract

Telah dilakukan pembuatan lapisan swabersih dari komposit TiO2-SiO2 di permukaan katun tekstil menggunakan metode dip-spin coating. Bahan yang digunakan berupa TiO2 dan SiO2 serbuk. Variasi TiO2-SiO2 yaitu 0,5; 1; 1,5; 2; 2,5;3. TiO2-SiO2 yang telah dibuat dilarutkan sebanyak 1% (b/v). Sebelum dicampurkan dengan larutan TiO2-SiO2, katun disterilkan dan direndam dalam asam asetat glasial yang berfungsi sebagai cross linking agent selama 15 menit. Katun terlapis TiO2-SiO2 diuji menggunakan larutan noda asam palmitat 15 ppm serta disinari selama 12 jam dibawah lampu UV. Absorban awal dan absorban akhir noda dihitung menggunakan spektrofotometer UV-Vis. Sampel yang telah dibuat dikarakterisasi menggunakan mikroskop optik, XRD dan SEM. Berdasarkan hasil penelitian diperoleh persentase pengurangan noda asam palmitat tertinggi dan terendah adalah 91,34% untuk penambahan 1,5 g SiO2 dan 3,80% untuk penambahan 3 g SiO2. Gambar dari mikroskop optik memperlihatkan lapisan TiO2-SiO2 pada katun mengalami peningkatan ketransparanan seiring meningkatnya penambahan komposisi SiO2. Morfologi katun terlapis TiO2-SiO2 dapat terlihat lebih jelas menggunakan SEM, dimana penambahan 1,5 gr SiO2 memiliki lapisan yang lebih tebal dan terjadi aglomerasi pada permukaan katun dibandingkan penambahan 3 g SiO2. Berdasarkan hasil XRD penambahan SiO2 mengakibatkan puncak TiO2 tertutupi.

Kata kunci: lapisan swabersih, cross lingking agent, asam asetat glasial, asam palmitat
