Polyimide (PI) has been considered to be suitable matrix polymers for advanced technological applications in the microelectronics and aircraft industries

because it possess excellent chemical

physical

thermal and mechanical properties.With the increasing and urgent market demand to produce higher-performance electronic devices with smaller size

lighter weight and better quality

the applications of PI are limited owing its high coefficient of thermal expansion and moisture absorption in higher-performance electronic devices at high temperature.To date

one of the best ways to improve properties of PI is to introduce nanometer materials into the PI matrix and yield polyimide nanocomposites of inorganic nanometer hybrid. In this paper

the preparation methods of polyimide hybrid materials were illustrated firstly.Then the normal types

properties and applications of polyimide hybrid materials were introduced.In addition

the tendency of polyimlde hybrid materials was predicted.
