| 摘 要： | 采用超声分散溶液共混法制备出聚氨酯/碳纳米管复合材料,探讨了聚氨酯溶解剂、碳纳米管分散剂以及成型工艺对复合材料的影响。结果表明:聚氨酯溶解液宜选用体积比为1∶1的四氢呋喃和N,N-二甲基甲酰胺,其溶解力为20 mL溶液72 h完全溶解1 g聚氨酯;碳纳米管分散液宜采用N,N-二甲基甲酰胺,超声分散时间为2.0 h;成型工艺宜采用混合溶液加热后放入真空干燥箱中干燥,再置于空气中凝固,得到表面平滑的聚氨酯/碳纳米管复合材料。

| Abstract: | In the paper, the polyurethane （PU）/carbon nanotubes （CNTs） composites were produced by ultra- sonic dispersion and solution-blending methods. The selection of PU dissolution and CNTs dispersing solution,and fabrication of composites were analyzed. The results showed that tetrahydrofuran and N, N - dimethylfomamide （DMF） could be used as resolving solution with 1 ： 1 ,and 1 g Pu was resolved with 20 mL solutions about 72 h. The DMF was used as the dispersion solution of CNTs with ultrasonic dispersion about two hours. The producing processes of PU/CNTs composites were successively to heat on the furnace, dry in the vacuum box, and solidify in the air. The smooth surface of composites could be produced. |
