Fabrication of Polyimide Nano-Particles by Precipitation Polymerization
نویسندگان
چکیده
Polyimides have been widely used as high-performance polymers, but controlling their morphology is still challenging. This study focuses on fabricating spherical polyimide particles by the precipitation polymerization of diamine and tetracarboxylic dianhydride monomers. Polyimide were prepared changing concentration structure monomers in presence a dispersant, effect these conditions size distribution are discussed. The crosslinking triamine monomer also described.

Optimal Fabrication of Nano Menthol/PEG Particles by Electrospraying
Background: L-menthol [(1R,3R,4S)-(-)-menthol] is a flavoring that is the main component of mint herb essential oils, especially of the Mentha piperita and Mentha arvensis species. Its low solubility in aqueous systems makes precise formulation necessary in the final products. Of the methods available for fabrication of nanoparticles for use in pharmaceuticals, electrospraying is easy and requi...
