Large-scale preparation method of three-dimensional porous nano composite cooling film
The invention discloses a large-scale preparation method of a three-dimensional porous nano composite cooling film. The CA-based cooling film material is prepared from 0.1-0.5 part of cellulose acetate, 1-5 parts of acetone, 20-100 parts of water, other auxiliary agents and 10-20 parts of nanometer microspheres. The three-dimensional porous nano-composite cooling film is prepared through synergistic matching of the cellulose acetate, nano-microsphere particles and other auxiliaries; the composite film is obtained in a cellulose acetate and nano-microsphere self-deposition mode; and three-dimensional pores are generated due to liquid volatilization in a film forming process. The film has the effect of enhancing infrared heat radiated to the space; the surface temperature of a base body can be remarkably reduced; rapid and strong cooling is achieved; and the film can achieve the purpose of effective cooling under the conditions that active cooling equipment such as external electric power is not needed and sunlight irradiation exists/does not exist.
本发明公开了一种三维多孔纳米复合降温薄膜的规模化制备方法。CA基降温薄膜材料由0.1‑0.5份醋酸纤维素、1‑5份丙酮、20‑100份水、其他助剂以及10‑20份纳米微球制备得到。本发明三维多孔纳米复合降温薄膜，是通过醋酸纤维素、纳米微球粒子和其他助剂三者协同配制备得到，其中采用醋酸纤维素与纳米微球自沉积方式获得复合薄膜，成膜过程中液体挥发导致三维多孔生成；该薄膜具有增强向太空辐射红外热量的效果，可显著降低基体表面温度，实现快速强降温，该薄膜在无需外部电力等主动降温设备、有/无太阳光照射的情况下，都能达到有效降温的目的。
