Abstract:

Two kinds of diamine monomers containing naphthalene were synthesized by 1-naphthaldehyde and 2,6-dimethylaniline or aniline. Novel polyimides containing naphthalene in the side chain were synthesized via a one-step high-temperature polycondensation. The structures of the polyimides were characterized by 1H NMR and FTIR. The resultant polyimides show high glass transition temperature, excellent thermal stability, good solubility in common organic solvents and excellent mechanical properties. In addition, the polyimide fibers were prepared by electrospinning, and the films and fibers show good hydrophobic property.

Key words: Polyimide, Solublility, Thermal stability, One-step synthetic method, Naphthalene
