In this study, a nonsolvent thermally-induced phase separation (NTIPS) method was first proposed to fabricate hydrophilically-modified poly(vinylidene fluoride) (PVDF) membranes to overcome the drawbacks of conventional thermally-induced phase separation (TIPS) and nonsolvent-induced phase separation (NIPS) methods. Hydrophilically-modified PVDF membranes were successfully prepared by blending ...

The formation of spherical micelles in aqueous solutions of poly(N-methyl-2-vinyl pyridinium iodide)-blockpoly(ethylene oxide), P2MVP-b-PEO and poly(acrylic acid)-block-poly (vinyl alcohol), PAA-b-PVOH has been investigated with light scattering-titrations, dynamic and static light scattering, and H 2D Nuclear Overhauser Effect Spectroscopy. Complex coacervate core micelles, also called PIC mic...

Poly(vinyl alcohol) (PVOH) based water-soluble packaging with intentional disposal into wastewater provides great convenience for both households and industry. In this paper, we demonstrate CO2 evolution testing that only insignificant fractions (~2%) of PVOH biodegrade in within 33 days. To avoid unintentional environmental build-up the accompanying consequences to marine life, alternative mat...

Stevia rebaudiana plant leaves were used for biosynthesis of gold nanoparticles (AuNPs). Transmission electron microscope images showed various shapes and sizes AuNPs. Various amounts AuNPs added to polyvinyl alcohol/carboxymethylcellulose (PVA/CMC, 40/60) via the casting method. The X-ray diffraction (XRD) spectrum pure blend shows amorphous nature blend. FTIR spectra interaction between PVA/C...
