| 제목 | A study about the thermal properties of electrospun polyhydroxyamide and its copolymers |
| 초록 | PBO(polybenzoxazol) and PI(polyimide) which are heterocyclic polymers have good mechanical properties and heat resistances, so they have attracted attention as a good heat resist material. Since they have poor processibility due to their rigid structure. PBO and PI still need an easier processing method. PHA(polyhydroxyamide), PAA(polyamic acid) copolymers specially designed for the precursors to PBO have different initial degradation temperature and degradation rates with PAA contents. and the numerical values are calculated by activation energy. The cyclization kinetics of the electrospun PHA or PHA complymer were compared with film samples. Since the increased surface area of the web many affect the cyclization chemistry and kinetics, it is considered that cyclization rate of the nanoweb is different from the film sample. |
