Polyimide (PI) was successfully hybridized with polysiloxanes by synchronizing two reactions; imidization of poly(amide acid) (PAA) and sol-gel process of diethoxysilanes. Diethoxydimethylsilane, diethoxymethylphenylsilane, and diethoxydiphenylsilane were used as precursors for the formation of polydimethylsiloxane (PDMS), polymethylphenylsiloxane (PMPS), and polydiphenylsiloxane (PDPS), respectively. The progress of sol-gel reaction was confirmed by IR. The compatibility of polysiloxanes with polyimide was studied by scanning electron microscopy, which revealed better compatibility of phenyl group containing polysiloxanes. The effect of the pendant group of polysiloxane on the mechanical and thermal properties of PI-polysiloxane hybrids was studied. Tensile strength of PI were increased by the addition of small amount of polysiloxanes. Hybrid containing 3 wt% of PDMS gave the highest tensile properties. Dynamic viscoelastic analysis of the PI-polysiloxane hybrid revealed two glass transition temperatures corresponding to polysiloxane and PI components. Thermogravimetric analysis revealed higher thermal stability by the hybridization.
