Different Molecular Weight

AbstractPoly(vinyl alcohol) (PVA) nanofibres were obtained by electrospinning of PVA/water solutions. Formation of beaded fibres combined with decreased fibre diameters was observed for low PVA concentrations. Electrospinning of blends of PVA of different molecular weight resulted in less bead formation and smaller fibre diameters as compared to corresponding homopolymers of similar viscosity.

Furnace Slag

High content amorphous phase blast furnace slag beads were prepared by gas quenching blast furnace slag (BFS), which could not only avoid a series of environmental problems caused by traditional water quenching methods, but also significantly increase the added value of BFS subsequent products. In this paper, the granulation mechanism of BFS and the amorphous phase formation mechanism of slag beads were studied by combining the physical properties of BFS and the granulation effect. The results showed that the viscosity of BFS decreased with the increase of basicity; the bigger the basicity, the higher the bead formation rate, the smaller the particle size and the more regular the slag shape. The smaller the basicity, the greater the crystallization activation energy and the smaller the Avrami exponent, which indicated that the crystal was more difficult to nucleate and grow. The increase of the cooling rate could effectively inhibit crystal precipitation. Therefore, the high basicity and cooling rate could not only guarantee the high bead formation rate of BFS, but also ensure the high content amorphous phase of slag beads.

Abstract In this study we aimed at finding different solvents for PVB and determine the effect of concentration and solvents on electrospun polyvinyl butyral (PVB) nanofibers. Firstly, we solved PVB in isopropanol, n-butanol, dimethylformamide, ethanol and acetic acid in various concentrations. Later, we compared fiber characteristics for each solvent. We observed that with increasing concentration, the fiber diameter increased. Bead formation occurred in low concentrations and low viscosity of polymer solution. Each solvent has a different effect on nanofiber morphology. It is observed that fiber diameter and morphology is one of the parameters that can be controlled by solvent.
