摘　　要：目的:在战争或突发事件时,血液长途运输时的冷链保证非常重要。为保证无电力保障情况下长时间血液运输的安全,文章旨在研制一种储血保温用复合相变材料。方法:利用毛细作用力和疏水性将正十四烷吸附到二氧化硅气凝胶的孔隙中,应用差热扫描量热法等检测变相材料性能。结果:二氧化硅气凝胶的比表面积为863.59m2/g、吸附率为9.16%;复合相变材料的相变温度和相变潜热分别为5.47℃和180 J/g。结论:正十四烷/二氧化硅气凝胶复合相变材料可用于血液储存。Objective ： Temperature keeping is vital in the long distance transportation of red blood cell suspensions in military affairs and emergency. This study aimed to develop a composite phase change material to be used for preserving blood in long time transporation without electricity. Methods： The n-tetradecane was adsorbed to the pore structure of silica aerogel through the capillarity and hydrophobicity of silica aerogel. The efficiency of the phase change material was detected by differential scanning calorimetry. Results： The specific surface area and the adsorption capacity were 863.59 m^2/g and 9.16, respectively. The phase change temperature was 5.47℃ and phase change latent heat was 180J/g. Conclusion ： The n-tetradecane/silica aerogel composite phase change material could be used for blood preservation.
