A series of polyimide (PI)/SiO _2 aerogel microspheres were prepared by using polyamide acid salt and hydrolyzed tetraethyl orthosilicate based on the reverse-phase emulsion method. Then, PI/SiO _2 aerogel microspheres were carbonized and etched to o

Polyimide aerogels generally face problems of shrinkage and collapse of pore structure during preparation, resulting in poor macro-structural integrity and mechanical properties. Towards these problems, polyimide composite aerogels with three-dimensi

A facile method for preparing porous polyimide aerogels was successfully developed. Poly (amic acid) solution composed by 2,2-bis(3,4-anhydrodicarboxyphenyl) hexafluoropropane and 4,4′-oxydianiline were synthesized in solvent dioxane or dioxane/t-b

Herein, we demonstrate a novel strategy for the fabrication of porous polyimide hollow microspheres through building oil-in-water-in-oil (O/W/O) multiple emulsion using poly(amic acid) salt (PAAS) water solution as W phase, liquid paraffin (Lp) as O

Nanoparticles (NPs) have proven to be effective drug carriers in diagnosis and therapy of cancer. But, they faced a contradictory issue that NPs with large size appear weak tumor penetration, meanwhile small size resulted in poor tumor retention. Her
