| 제목 | Synthesis of temperature responsive polymer particles in supercritical carbon dioxide |
| 초록 | The temperature responsive poly(N-isopropylacrylamide) (PNIPPAm) have been widely used in biomedical applications, such as drug controlled release systems, drug carrier and so on. Supercritical carbon dioxide is considered as a useful alternative of toxic or volatile organic solvents for polymer synthesis and processing. Main advantages to use scCO2 as a polymerization medium are that it is less-toxic, non-flammable, chemically inert and naturally abundant than many other organic solvents. We carried out polymerization N-isopropylacrylamide with AIBN as the initiator using dispersion polymerization methods in supercritical carbon dioxide. And the spherical polymer particles were prepared using fluorinated dispersant and N,N’-methylenebisacrylamide (MBIS) as cross-linking agent. The polymerizations were prepared in scCO2 at various temperature and pressure ranges. The resulting polymer was characterized by FE-SEM, DSC, TGA and 1H-NMR etc. |
