A microwave absorption nanocomposite is prepared by polyaniline (PANI) coated Fe3O4 nanoparticles and polybenzobisoxazole (PBO), the latter being a conjugated polymer with high mechanical strength and outstanding thermal and oxidative stability. Fe3O4@PANI nanoparticles are well dispersed in the PBO matrix to form PBO/(Fe3O4@PANI) nanocomposite, which has excellent thermal stability (high char yield...
In this study, titanium alkoxide catalyst dependences of condensation polymerization, thermal degradation and stability were examined for a biodegradable aliphatic poly(tetramethylene succinate) (PTMS). A series of aliphatic PTMSs were synthesized through polycondensation of 1,4-butanediol and succinic acid in bulk with various amounts of titanium tetraisopropoxide (TTiPO) as the catalyst, and were...
