Popis:	The characterization of dressing component materials and radiation induced formation of PVA–PVP hydrogel have been carried out. It was found that the purity of PVA and PVP powders were 99.5% and 77.82% based on DSC measurement. The PVA–PVP hydrogels have the water content in the range of 60–80% and water absorption in the range of 40–250%. It was also found that the PVA–PVP hydrogel prepared by irradiation at 20 kGy shows a good barrier for microbes. This characterization are very important for PVA–PVP hydrogel to be used as wound dressing.
