Development and Application of Organic Aerogel in the Context of Low Carbon Energy Conservation
Since the advent of the sustainable development era,energy conservation and environmental issues have increasingly garnered attention from the scientific research community and industry.Renewable and eco-friendly materials play a crucial role in achieving emission reduction and addressing environmental challenges.Aerogels,characterized by their three-dimensional continuous network structure,large specific surface area,high porosity and low thermal conductivity come in various types with diverse preparation methods,has become one of the new materials.Among them,organic aerogels stand out due to their distinctive features such as lightweight,high specific surface area,and high porosity,presenting broad applications in thermal insulation,flame retardancy,adsorption,and energy storage capacitance.This paper based on the main classification of organic aerogels(polysaccharide aerogels,synthetic aerogels,etc.),provides a comprehensive review of the research focal points,preparation methods,material properties,functional modifications and current application status of several organic aerogels reported in recent years.The preparation methods of wet gels and the characteristics of different drying processes in the preparation of aerogel were summarized.Meanwhile,briefly outlines the diverse methods for functionalizing and modifying current organic aerogels,and the application scenarios and directions of organic aerogel obtained by different modified preparation processes in practical applications were summarized.Finally,prospered the future development direction of organic aerogel,and emphasized the importance of further improving the material properties,optimizing the preparation process and expanding the application field.It is hoped that the in-depth study of organic aerogel will promote its wider application in the field of sustainable development and make greater contributions to the development of environmentally friendly materials.
