Alpha (alpha) PP tapes of different draw ratios (DR = 8 and 12), produced by online extrusion stretching, served as reinforcements. Beta (beta)-nucleated random PP copolymer, introduced in the form of a film, composed the matrix. The E-modulus of the PP tapes increased whereas their density decreased with increasing DR. The volume fraction of the reinforcement and the void content were estimated using optical microscopic images. The all-PP composites were subjected to dynamic mechanical thermal analysis, flexural, and instrumented falling weight impact tests. It was found that with increasing draw ratio of the alpha-PP tapes, the stiffness, strength, and perforation resistance of the composites were improved.</p>10aall-polypropylene composite10adraw ratio10adynamic mechanical thermal analysis10ainstrumented falling weight impact10apolypropylene1 aAbraham, Thomas, N.1 aWanjale, S.1 aSiengchin, S.1 aKarger-Kocsis, Jozsef  uhttps://library.ncl.res.in/content/dynamic-mechanical-and-perforation-impact-behavior-all-pp-composites-containing-beta-001813nas a2200289   4500008004100000022001400041245008800055210006900143260009500212300001000307490000800317520080700325653002001132653002501152653001401177653000901191653003301200100002101233700002801254700002401282700002101306700002001327700002601347700001701373700002001390856011301410       2016                        eng d  a0021-979700aSurface tailored PS/TiO2 composite nanofiber membrane for copper removal from water0 aSurface tailored PSTiO2 composite nanofiber membrane for copper   a525 B ST, STE 1900, SAN DIEGO, CA 92101-4495 USAbACADEMIC PRESS INC ELSEVIER SCIENCEcMAY  a31-370 v4693 a<p>Polystyrene (PS)/TiO2 composite nanofiber membranes have been fabricated by electrospinning process for Cu2+ ions removal from water. The surface properties of the polystyrene nanofibers were modulated by introducing TiO2 nanoparticles. The contact angle of the PS nanofiber membrane was found to be decreased with increasing concentration of TiO2, depicted enhanced hydrophilicity. These membranes were highly effective in adsorbing Cu2+ ions from water. The adsorption capacity of these membranes was found to be 522 mg/g, which is significantly higher than the results reported by other researchers. This was attributed to enhanced hydrophilicity of the PS/TiO2 composite nanofiber membranes and effective adsorption property of TiO2 nanoparticles. (C) 2016 Elsevier Inc.
