Abstract

Materials with potential of fast absorption of water or liquid have emerged as very interesting objects for researches. Superabsorbent polymer is a cross linked polymer which has ability to absorb water hundreds to thousands of times the dry weight because it has hydrophilic groups. Owing to this characteristic this polymer gets attention for many applications, one of these is diapers. Superabsorbent polymer was synthesized from the mixture of glucomannan-pottasium acrylic-acrylamide solution by irradiation crosslinking with doses irradiation 10 kGy. It was found that SAP showed super swelling properties in water (880 g/g) at short time (15 minutes) and in real urine has a good swelling 110 g/g. Acrylamide was able to increase the swelling ratio in real urine. Therefore, it can be candidate as thin diapers with high sorption. The result of FTIR spectra confirmed that the crosslinking occurs in the hydrogels and SEM images of hydrogels showed large numbers of pores from SEM examination Keywords: Superabsorbent polymer; Acrylic acid; Acrylamide; Glucomannan; Irradiation

伽马辐射合成高吸水性高分子葡甘露聚糖聚丙烯酸酯

具有快速吸收水或液体潜能的材料已成为研究的热点。高吸水性聚合物是一种交联聚合物，由于具有亲水性基团，具有吸附干重数百至数千倍的水的能力。由于这种特性，这种聚合物得到了许多应用的关注，其中之一就是尿布。以葡甘露聚糖-丙烯钾-丙烯酰胺溶液为原料，采用辐照交联法制备了高吸水性聚合物，辐照剂量为10 kGy。结果表明，SAP在水中(880 g/g)在短时间内(15分钟)具有超强的溶胀性，在真实尿液中具有良好的溶胀性110 g/g。丙烯酰胺能够增加真实尿液中的溶胀率。因此，它可以作为高吸附性的薄纸尿裤的候选人。FTIR光谱结果证实了水凝胶中存在交联反应，并且水凝胶的SEM图像显示出大量的孔隙。丙烯酸;丙烯酰胺;葡甘露聚糖;辐照
