Advancements in nanotechnology and materials science have led to an increased demand for specific material functions, preparation, design of polymer particles with ordered internal surface mesostructures. In this work, well-shaped spheres poly(2,2,2-trifluoroethyl methacrylate)-b-poly(2-vinylpyridine) four different molecular weights are prepared by 3D confined self-assembly. After thermal anne...

This paper considers the effect of mutual activation poly(methacrylic acid) (PMAA) and poly-(4 vinylpyridine) (P4VP) hydrogels during their remote interaction on degree yttrium ions sorption from an aqueous medium. Electrochemical properties were studied by conductometry pH measurements to predict possibility these hydrogels. showed that at 0.1 hour, values lowest, indicating a high content H+ ...

Sand, an abundant resource from the nature, is a promising candidate for oil/water separation. Herein, raw sand was designed with switchable surface wettability to enable recyclability and versatility in practical The “smart” fabricated by grafting pH-responsive poly(4-vinylpyridine) (P4VP) oleophilic/hydrophobic octadecyltrimethoxysilane (OTS) onto its surface. decorated can be used as oil sor...
