Pure poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) and zinc oxide (ZnO)/PHBV composite nanofibers were fabricated by an electrospinning method. ZnO nanoparticles (NPs) with a diameter of about 10–20 nm were doped in the PHBV fibers and no dispersion agent was utilized. Both pure PHBV and composite electrospun fibers were smooth and uniform. ZnO NPs did not affect the basic crystalline structure...
Most magnetic materials possess serious sedimentation problem due to their large density when they are adopted as magnetorheological (MR) materials. In this communication, we fabricated novel core–shell structured polystyrene(PS)/Fe 3 O 4 microbeads via a facile method. Porous morphology of the PS obtained by etching silica particles and the loaded Fe 3 O 4 was observed...
Comments on the recent studies of electrorheological (ER) properties of hydrosoluble β-cyclodextrin polymer based ER fluids are given based on the analysis of their yield stress data as a function of applied electric field strengths. Using our previously reported universal yield stress equation and critical electric field strengths deduced, it is found that we can collapse their data into a single...
