Abstract:
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 m2/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.
