A polyimide composition varnish, comprising:
- a polyimide or a polyimide precursor;
- and
- an organically modified layered silicate in which interlayer ions are replaced with organic phosphonium ions.
A method of manufacturing a polyimide composition varnish, the method comprising:
- forming a dispersion by dispersing a layered silicate in water while heating;
- forming an organically modified layered silicate by adding organic phosphonium ions to the dispersion and stirring, removing a supernatant by separating a solid and a liquid, adding a mixed solution of water and ethanol and stirring, and removing a supernatant by separating a solid and a liquid;
- forming an organically modified layered silicate dispersion by adding an organic solvent to the organically modified layered silicate and stirring;
- and
- adding the organically modified layered silicate dispersion to a polyimide or a polyimide precursor and mixing.
