Abstract

Quantum Dots CuInS2 (QDs CIS) merupakan semikonduktor dengan sifat menarik seperti koefisien penyerapan tinggi, fluoresensi yang dapat disesuaikan. Polyacrylonitrile (PAN) terkenal dengan sifat mekaniknya yang tinggi, stabilitas termal, dan kelembaman kimia. Polycaprolactone (PCL), polimer sintetik yang dapat terdegradasi, aman, dan tidak beracun. Penelitian ini bertujuan untuk menganalisis karakteristik morfologi, sifat mekanik, kemampuan filtrasi, permeabilitas udara, dan hidrofobiksitas dari komposit nanofiber PAN/PCL/CIS QDs. Metode electrospinning digunakan dalam fabrikasi nanofiber tersebut. Hasil penelitian ini menunjukkan, fabrikasi komposit nanofiber PAN/PCL/CIS QDs dapat dilakukan dengan menggunakan metode electrospinning pada tegangan 15 dan 20kv. Tegangan yang lebih besar cenderung menghasilkan diameter nanofiber yang besar. Penambahan CIS maupun CIS-TO ke dalam nanofiber membuat menurunnya sifat mekanik dari nanofiber namun meningkatkan kemampuan hidrofobiknya. Seluruh nanofiber dalam penelitian ini memiliki kemampuan efisiensi filtrasi terhadap PM2,5 >98% dan memiliki hambatan udara sebesar 60-68%.

Quantum Dots CuInS2 (QDs CIS) is a semiconductor with attractive properties such as high absorption coefficient, adjustable fluorescence. Polyacrylonitrile (PAN) is well known for its high mechanical, thermal, and chemical inertness properties. Polycaprolactone (PCL), a biodegradable, safe and non-toxic synthetic polymer. This study aims to analyze the morphology, mechanical properties, filtration ability, air permeability, and hydrophobicity of PAN/PCL/CIS QDs nanofiber composites. Electrospinning method used in the fabrication of the nanofiber. The results of this study indicate that the fabrication of PAN/PCL/CIS QDs nanofiber composites can be carried out using the electrospinning method at a voltage of 15 and 20kv. larger connections tend to result in larger nanofiber diameters. The addition of CIS and CIS-TO into the nanofiber reduces the mechanical properties of the nanofiber but increases its hydrophobic ability. All of the nanofibers in this study had an efficiency capability of PM2.5 >98% and had an air resistance of 60-68%.
