以聚四氢呋喃二醇、环状脂肪族二异氰酸酯和偏二胺为原料，合成了一种嵌段聚氨基甲酸酯。该共聚物的尿素含量为35wt%。研究了该弹性体聚氨酯尿素共聚物在溶液中的静电纺丝行为。研究了电场、温度、电导率和溶液粘度对静电纺丝工艺及纤维形态和性能的影响。对光学显微镜、原子力显微镜和扫描电子显微镜的观察结果进行了解释，并与有关其他聚合物体系电纺行为的文献数据进行了比较。(C)2002爱思唯尔科学有限公司。保留所有权利。
A segmented polyurethaneurea based on poly (tetramethylene oxide)glycol, a cycloaliphatic diisocyanate and an unsymmetrical diamine were prepared. Urea content of the copolymer was 35 wt%. Electrospinning behavior of this elastomeric polyurethaneurea copolymer in solution was studied. The effects of electrical field, temperature, conductivity and viscosity of the solution on the electrospinning process and morphology and property of the fibers obtained were investigated. Results of observations made by optical microscope, atomic force microscope and scanning electron microscope were interpreted and compared with literature data available on the electrospinning behavior of other polymeric systems.
