The scope of hydrogel applications can be greatly expanded by the improvement of mechanical properties. However, enhancement of nanocomposite hydrogels (NC gels) has been severely limited because the size of crosslinking nanoparticles is too large, at least in one dimension. Here we report a new strategy to synthesize non-aggregated spherulite nanoparticles, with diameters <5 nm, in aqueous sol...

Abstract Some anisotropic materials form semicrystalline structures, called spherulites, when observed in a polarisation microscope, exhibit characteristic “maltese-cross”-like pattern. While this observation has been hitherto considered as tool to characterize these materials, we show that patterns are associated with strong light’s spin–orbit coupling induced by the spherulite structures. We ...

We have introduced a novel solvent-based method to roughen polymer surfaces and characterized treated polypropylene (PP). The consists of three main steps: solvent treatment, drying, peeling. investigated the effects process parameters such as time immersion in solvent, temperature, drying temperature on surface morphology created. structure formed is mainly influenced by temperature. also wett...
