Fabrication of Size-controlled Hollow Polyimide Microsphere with Simple Template-free Method |
| 초록 |
The fabrication of hollow polyimide (HPI) microparticles was carried out by the electrospraying process (ESP). Polyimide (PI) particles can be controlled to have the hollow structure by tailoring the spraying mode during the ESP. New apparatus was designed to collect HPI microparticles using heat-resistance silicone oil acting as thermal imidization medium. The mean diameters of the hollow microspheres were controlled in the range from 10 up to 100 um by the polymer concentration, the flow rate and the applied voltage. The results demonstrate that this method provides the simple template-free fabrication for HPI particles, which retains a hollow shape without deformation of the shell at a high temperature of 200oC or higher. |
