Abstract

A research has been conducted to determine the effect of Polyethylene Glycol Diacrylate (PEGDA) on the properties of crosslinked hydrogel film. The composition of Polyethylene Glycol Diacrylate (PEGDA)/Polyethylene Oxide (PEO) concentration was 0 to 30% (by weight). The hydrogel films were produce by electron beam irradiation process at 300 kGy dose to obtaining crosslinked. The measured characteristics included gel fraction, swelling ratio, vapor transmission rate, and mechanical properties. The chemical structure was analysed using Spektrofotometer Fourier Transform-Infra Red (FT-IR). The research result showed that the gel fraction value increased with increasing PEGDA content. Meanwhile, the swelling ratio value decreased with addition concentration PEGDA. The hydrogels strength tended to increase from 2.22 to 5.66 N/m2 and its elastic modulus, having the highest value of 193.65 MPa. Due to the high PEGDA content of hydrogel. The elongation of hydrogel decreased with increase PEGDA content with the lowest value of 530.6267%. The rate of vapor transmission reached the highest value of 3.02 g / m2h with 10% PEGDA content. The result showed that the addition of PEGDA content can improve the tensile strength, elastic modulus, and vapor transmission demonstrate the possibility of mechanically robust and be expected can be used for wound dressing applications.
