摘要:通过自由基聚合一步合成了羟乙基纤维素/聚丙烯酰胺(HEC/PAM)复合水凝胶,这种水凝胶具有优异的拉伸性能和压缩性能,可能源于PAM链与HEC链之间的氢键相互作用。经测试,HEC/PAM复合水凝胶可被拉伸至原尺寸的24倍,对应的拉伸断裂应力为113kPa;90%压缩形变对应的压缩强度达0.87 MPa;水凝胶的最大压缩形变达95%以上。同时,HEC/PAM水凝胶还表现出了优异的可恢复性能。因此,HEC/PAM复合水凝胶在生物医药领域有潜在的应用价值。
Hybrid hydroxyethyl cellulose /polyacrylamide (HEC/PAM) hydrogels with excellent tensile and compressive properties were successfully prepared by one-step free-radical polymerization. The hydrogen bonds between the PAM chains and I-IEC chains mainly contributed to the good mechanical properties of hybrid hydrogels. The HEC/PAM hybrid hydrogels exhibit an extremely large elongation at break of 2400 %, and a fracture stress of 113 kPa; they could reach a strain of over 95% without break; the compressive stress at 90% of these hybrid hydrogels reaches as high as 0.87 MPa. Meanwhile, HEC/PAM hybrid hydrogels exhibit excellent recoverable performance. Thus, the HEC/PAM hybrid hydrogels could be potentially applied in biomedical fields.
