| 제목 | Synthesis and Characterization of Polyimide/Aromatic Polysilsesquioxane Hybrid Nanocomposites |
| 초록 | Polyimide (PIs) have been widely studied in microelectronic industry because of their outstanding thermal chemical stabilities, high tensile strength and modulus, and good dielectric properties. Recently, Organic/Inorganic hybrid materials have been widely studied because novel materials properties can be produced through systematic design of the organic and inorganic segments. In this work, polyimide hybrid nanocomposites film will prepare using an in situ sol-gel reaction followed by multi-step curing. For this work, three different aromatic polysilsesquioxane (PSSQ) were synthesized. PI was prepared from 3,3',4,4'-biphenyltetracarboxylic dianhydride (BPDA) and oxydiphenylenediamine (ODA) poly(amic acid). PI/aromatic PSSQ hybrid nanocomposite films were characterized by FT-IR spectra and FT-Raman spectra. TGA results suggest the thermal stability of the hybrid films increased with introducing inorganic moieties into the PI matrix. TGA curves of the PI/aromatic PSSQ hybrid films (a)Pure PI, (b)PI-o-MPP15, (c)PI-m-MPP15, (d)PI-p-MPP15, (e)PI-o-MPP30, (f)PI-m-MPP30, and (g)PI-p-MPP30 |
