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。
