Porous Polyimide Membranes Prepared by Wet Phase Inversion for Use in Low Dielectric Applications
A wet phase inversion process of polyamic acid (PAA) allowed fabrication of a porous membrane of polyimide (PI) with the combination of a low dielectric constant (1.7) and reasonable mechanical properties (Tensile strain: 8.04%, toughness: 3.4 MJ/m3, tensile stress: 39.17 MPa, and young modulus: 1.13 GPa), with further thermal imidization process of PAA. PAA was simply synthesized from purified...

Preparation of basil seed mucilage aerogels loaded with paclitaxel nanoparticles by the combination of phase inversion technique and gas antisolvent process
Objective(S): In this work, paclitaxel (PX), a promising anticancer drug, was loaded in the basil seed mucilage (BSM) aerogels by implementation of supercritical carbon dioxide (SC-CO2) technology. Then, the effects of operating conditions were studied on the PX mean particle size (MPS), particle size distribution (PSD) and drug loading efficiency (DLE). <stron...
متن کاملPreparation of nanoemulsions by phase inversion temperature (PIT) method
Over the last decade, nanoemulsion-based delivery systems have been gained interest in the pharmaceuticals1-4, food and beverage5-8, cosmetics9-11, agrochemicals12-14 and other15 industries. The main purposes are to encapsulate, protect, and deliver lipophilic components such as drugs, vitamins, food supplements, antioxidants, antimicrobials, pesticides. In general, it is desirable to utilize n...
متن کاملPreparation of microporous poly(vinylidene fluoride) membranes via phase inversion in supercritical CO2
Microporous poly(vinylidene fluoride) (PVDF) membranes were prepared from PVDF/N,N-dimethylacetamide (DMAC) solutions by using upercritical CO2 phase inversion process. As revealed by scanning electron microscope (SEM) and differential scanning calorimeter (DSC), he PVDF membranes exhibit morphological characteristics resulting from both liquid–liquid phase separation and crystallization, i.e.,...
