Abstract

Low density polyethylene films with a thickness of 50 μm were surface modified by oxygen plasma using an Ion Shower Equipment. The contact angle was reduced from 90° to 24.34°, effectively rendering the surface hydrophilic. From AFM results, surface roughness was increased from 30.08 nm to about 47.73 nm for a 10x10 μm² scan area. FTIR-ATR spectra confirms a decrease in C-C (1450- 1500 cm^-1) and C-H bonds (3000-2750 cm^-1 ,700-750 cm^-1), an increase in polar groups from carbonyl C=O (1750-1600 cm^-1), carboxyl COO^-1(1650-1560 cm^-1, 1400-1310 cm^-1) and hydroxyl groups (680-580 cm^-1, 3700-3600 cm^-1) accounts for increase in wettability of material.
