摘要: To control the morphology of the particles prepared from high-concentration solution under severe preparation conditions, an organic polymeric precursor solution was introduced in spray pyrolysis. In the aqueous solution, hollow particles were formed by the surface precipitation because of rapid drying rate of droplet in the severe preparation condition. On the other hand, in the polymeric precursor solution, the polymeric chain formed from the esterification reaction between carboxyl and hydroxy groups of citric acid (CA) and ethylene …
