摘要:
为缓解高温天气带来的负面影响,可采用经济节能的冷却材料。以天然竹为原料,采用两步法进行脱木质素处理,通过喷涂法引入SiO2粒子,并根据纤维素和SiO2粒子的多级结构和辐射特性,制备具有日间被动辐射制冷性能的降温材料竹纤维/SiO2复合膜;对竹纤维/SiO2复合膜进行结构表征,探究其光谱特性及降温性能。结果表明:SiO2成功引入竹纤维/SiO2复合膜中;与原竹相比,竹纤维/SiO2复合膜的太阳光反射率提高至90.1%;竹纤维/SiO2复合膜在大气窗口范围内的红外发射率约97.9%;在户外条件下,辐照强度为546 mW/cm2时,竹纤维/SiO2复合膜与原竹相比可降低温度约7-8 ℃,红外热成像也证明竹纤维/SiO2复合膜具有良好的降温性能。该竹纤维/SiO2复合膜有较好的降温效果,具有较大应用潜力。
