Abstract
To investigate the influence of reactant structure on gel process and aerogel structure, aerogels were prepared with different reaction systems. The influence of reactant structure on gel process was investigated, and the structure of aerogels was also investigated by means of scanning electron microscope (SEM) and surface area and pore size analyzer. The results show that reactivity and steric affect of reactants effect the gelation time together. Gel can not be formed if reactants were chosen wrongly. Aerogel structure is different with the change of reaction system. The surface area of 5-methyl furfural resorcinol (MR-F) aerogel is 25% bigger than that of resorcinol furfural(RF) aerogel, and the micropore surface area and pore volume of MR-F aerogel are 3.6 times and 9.6 times bigger than those of RF aerogel respectively.
