摘要
Abstract
The focus of this work was to effectively control the porosity of microspheres prepared via electrospraying, which would establish the foundation for the following application. Scanning electron microscopy （SEM） and thermogravimetry （TG） were employed to evaluate the morphology and the porosity of microspheres, respectively. According to the investigation result, adding hydrophilie polymer polyethylene glycol （PEG） and polyving akohol （PVA） to eleetrosprayed solution could effectively control the porosity of microspheres. Specifically adding hyctrophilie polymer could improve porosity; and that, with increasing hydrophilic polymer, the porosity of mierospheres first increased and then decreased; the control effect of PVA for the porosity of mierospheres was better than that of PEG, when the addition of PVA was 3%, the porosity of microspheres was the highest value of 91.35 %.关键词
