本刊讯近日,中国科学院青岛生物能源与过程研究所生物基材料院重点实验室开发出新型聚氨酯材料,有望打破国外企业对此类材料的垄断。研究人员通过亲水性聚氨酯树脂分子结构设计,调整了聚合物中链段排布方式及功能基团的密度,促使凝胶时形成均匀而致密的交联网络,突破相关关键技术,合成了具有高抱水量(最高可达为自身体 Recently, the Chinese Academy of Sciences Qingdao Institute of Bioenergy and Biobased Materials Research Institute Key Laboratory of new polyurethane materials developed is expected to break foreign monopoly of such materials. Through the molecular structure design of hydrophilic polyurethane resin, the researchers adjusted the arrangement of segments in the polymer and the density of functional groups to promote the formation of a uniform and dense crosslinked network during gel formation. Breakthrough in the relevant key technologies led to the synthesis of High hold water (up to the body
