Sifat Fisis Komposit Polietilen/Nanotitania Sebagai Fungsi Ketebalan

Abstrak

Physical properties of polyethylene (PE)/nanotitania composite as a function of thickness have been studied. The material used is PE and nanotitania. The blending of PE with nanotitania was carried out by melting polyethylene at 95 C for 5 minutes then added nanotitania 5 wt% and 10 wt% and heated at 124 C for 30 minutes. Then printed using barcoater with size 6, 12 and 25 m with four repetitions. Variations were performed to determine the effect of composite thickness of polyethylene/nanotitania on electrical properties and functional groups. FTIR results show that as the thickness of the absorption sample increases, new functional groups appear, namely hydroxyl and carbonyl. The LCR results show the smallest conductivity value, sample 5 wt% PE / nanotitania with 6 m size and the largest 10% PE/nanotitania sample with a size of 25 m each at 2,302 x 10^-5 S/m and 3,121 x 10^-5 S/m at a frequency of 10⁵ Hz. While the largest dielectric constant value is a sample of PE/nanotitania 5 wt% with a size of 6 m and the smallest sample PE/nanotitania 10 wt% with a size of 6 m at a frequency of 10⁵ Hz. Based on these characteristics, the 5 wt% PE/nanotitania sample with a size of 6 m is the material with the best dielectric properties so that the sample has the potential to be used as a cable insulator.
