Abstract

In this work, agar (AG) films have been prepared using the cast method technique. Surface properties such as contact angle (CA) and morphology of the
films were carried out. The water contact angle on the surface of agar film was recorded to be 74.91 ±0.35 indicating good hydrophilicity of the surface, which was confirmed by the scanning electron microscope (SEM) image of the AG film. The contact angle was also studied with the variation of time. After making the initial contact on the substrate, the water contact angle on the AG film was found to decrease gradually with time. Studying the oxygen permeability of the agar film showed that the film had an oxygen permeability of about 187 barer.
