摘要 以聚乙烯醇(PVA)、部分中和的丙烯酸(AA)和羟基磷灰石(HA)为原料,过硫酸铵(APS)为引发剂,N,N′-亚甲基双丙烯酰胺(MBA)为交联剂,采用水溶液聚合法制备了聚乙烯醇/聚丙烯酸/羟基磷灰石(PVA/PAA/HA)复合高吸水树脂。考察了PVA用量对吸水性能的影响,研究了树脂在不同pH值溶液和不同阳离子盐溶液中的溶胀行为。结果表明,引入适量的PVA有利于树脂吸水性能的改善;树脂在pH=4~11较宽的范围内都能保持较高的吸水倍率,在CaCl2溶液中的溶胀动力学行为表现出明显的"过溶胀平衡现象"。 A novel poly(vinyl alcohol)/poly(acrylic acid)/hydroxyapatite (PVA/PAA/HA) superabsorbent composite was synthesized through aqueous solution polymerization of partially neutralized acrylic acid (AA),poly(vinyl alcohol) (PVA) and hydroxyapatite (HA),using ammonium persulfate (APS) as an initiator and N,N′-methylenebisacrylamide (MBA) as a crosslinker.The effect of PVA content on water absorbency was studied.The swelling behaviors in various pH solutions and swelling kinetics in 2 mmol/L NaCl and CaCl2 saline solutions were also systematically investigated.Results show the introduction of proper amount of PVA into the polymeric network can improve water absorbency of the superabsorbent.Swelling behaviors reveal that the superabsorbent composites retain high water absorbency over a wide pH range of 4~11,and the swelling kinetics of the superabsorbent composite hydrogel in CaCl2 solution exhibits a remarkable overshooting phenomenon.
