| 摘要: |
| 现阶段以磁控溅射法制备的掺杂钨二氧化钒控温薄膜,其热滞回线陡峭、机械加工性能以及强度性能较差,为解决上述问题,采用湿法非织造法制备了红外光学性能优异、相变温度较低的纳米掺杂钨二氧化钒(W-VO2)纸基控温材料.使用差示扫描量热法(DSC)、扫描电子显微镜(SEM)、傅里叶变换红外光谱仪(FT-IR)等分析方法,对纳米W-VO2纸基控温材料的微观结构及红外相变特性等方面进行了分析,并对纳米W-VO2纸基控温材料的红外透射率及相变特性进行表征.结果表明:表面改性处理后可促进纳米W-VO2晶粒均匀分散,采用湿法非织造法制备的纳米W-VO2纸基控温材料,能够将相变温度控制在45 ℃附近,使红外透射率前后对比值达到37.5 %,实现了对红外波段透射率差值的优化；当纳米W-VO2控温材料加填量达到15 mL时,抗张指数、撕裂指数、耐破指数和耐折次数分别为7.62 kN/m、23.97 mN·m2/g、5.37 kPa·m2/g和92次(分度值14.7 N),为深入研究智能控温包装材料提供了参考依据. |

| Abstract: |
| At present, the temperature-control films of W-VO2 (M) prepared by magnetron sputtering method have a steep hysteresis loop with poor mechanical and strength properties. In order to solve the above problems, nano W-VO2 (M) temperature-control paper materials that have excellent infrared optical property and low phase-change temperature were prepared by wet-nonwoven method. The experiment analyzed the microstructure and infrared phase-change characteristics of the nano W-VO2 (M) temperature-control paper materials by using DSC, SEM, and FT-IR analytical methods, and characterized the infrared ray transmittance and phase-change property of nano W-VO2 (M) temperature-control paper materials. Results show that the surface modification couled improve the dispersity of the nano W-VO2 (M) grain , and the nano W-VO2 (M) temperature-control paper materials could maintain the phase-change temperature at about 45 ℃. The ratio of infrared transmittance reached 37.5%, which improved the infrared transmittance interpolation. When the dosage of nano W-VO2 (M) temperature-control materials was 15 ml, the value of tensile index, tear index,burst index, and folding times were 7.62 kN/m, 23.97 mN·m2/g, 5.37 kPa·m2/g, and 92 times (Resolation: 14.7 N), which provided reference for further research on the field of intelligent temperature-control packing paper field. |
