| 摘 要： | 将经过表面修饰的纳米二氧化锑掺杂二氧化锡(ATO)悬浮液加入到预热浴中,对聚丙烯腈(PAN) 纤维进行抗静电改性。讨论了悬浮液ATO含量和添加位置对纤维抗静电性、力学性能等的影响,采用差示扫描量热仪、X射线衍射、透射电镜对改性纤维的结构进行了分析。结果表明:当ATO质量分数为5％以上时,改性PAN纤维的电阻率下降到108 Ω·cm,纤维的断裂强度保持2．7 cN／dtex,改性PAN纤维耐水洗性好,且不同ATO含量的改性PAN纤维的结晶形态和结晶度接近,玻璃化转变温度也没有明显的变化,维持约100℃。

| Abstract: | The suspension of antimony dioxide incorporated with stannum dioxide(ATO) was exposed to surface modification and added into preheating bath for the antistatic modification of polyacrylonitrile (PAN) fiber. The structure of modified PAN fiber was analyzed by DSC, X-Ray and TEM. The effects of ATO suspension content and preheating bath location on the antistatic and mechanical properties of PAN fibers were discussed. The results showed that the modified PAN fiber had the specific resistance 108 Ω·cm and breaking strength 2. 7 cN/dtex when the ATO content was above 5% by mass fraction. The modified PAN fibers showed good washing resistance and exhibited the similar crystal morphology and crystallinity at different ATO content. The glass transition temperature of the modified PAN fibers showed no obvious variation and remained at 100℃. |
