[目的]研制一类新型的纳米遮阳降温复合材料,该类材料能有效控制温室光照强度并降低室内温度,且可反射红外光并将入射光转变为更利于植物进行光合作用的蓝紫光和散射光。[方法]利用熔融插层法制备了新型的纳米遮阳降温复合材料,采用FA、XRD、TG、UV-Vis-NIR等对纳米降温材料的结构和性能进行了表征。[结果]跟踪测定了不同类型的纳米降温材料的降温效果,表明这种单层共挤制备的纳米遮阳降温材料能有效降低棚内温度3-4℃。[结论]纳米遮阳降温复合材料是对农业增效,农民增收做出了重要贡献的农业生产资料,具有广泛的应用前景。

[Objective] The research developed a new kind of nano sun shading films that can be used in summer to maintain the appropriate indoor temperature for crops. [Method] The nano sun shading films were prepared by intercalation method. The films were characterized by XRD, TG, FA, UV-Vis-NIR and outdoor temperature test. [Result] Based on evaluation of cooling efficiency, a reduction 3-4 ℃ can be observed in newly developed nano sun shading films compared to control film. This film can control greenhouse light intensity effectively and decrease indoor tempera- ture, providing crops with appropriate growing temperature by reflecting most of in- frared light. Moreover, part of incident light can be converted to blue light and red light, which is beneficial to photosynthesis in plant. [Conclusion] Agricultural film is an important component to agriculture industry. Thus, agricultural film with improved properties and low cost has a broad application prospect.
