Selective permeation properties of ions through piezodialysis membrane
Wiley - Tập 29 Số 2 - Trang 709-712 - 1984
Manabu Igawa, Toshimitsu Tachibana, Masao Tanaka, Manabu Senō
Preparation and characterization of PET/silica nanocomposites
Wiley - Tập 91 Số 2 - Trang 1229-1232 - 2004
Wentao Liu, Xingyou Tian, Ping Cui, Yong Li, Kang Zheng, Ye Yang
AbstractPoly(ethylene terephthalate) (PET)/silica nanocomposites were fabricated by direct polymerizing PET monomer dispersed with organic modified silica nanoparticles. The characteristics and properties of these nanocomposites were investigated by the transmission electron microscopy, differential scanning calorimetry, and thermogravimetric analysis, respectively. The results show that (1) the n... hiện toàn bộ
Improved dispersion of clay platelets in poly(butylene terephthalate) nanocomposite by ring‐opening polymerization of cyclic oligomers: Effect of the processing conditions and comparison with nanocomposites obtained by melt intercalation
Wiley - Tập 114 Số 5 - Trang 3211-3217 - 2009
Corrado Berti, Enrico Binassi, Martino Colonna, Maurizio Fiorini, Tommaso Zuccheri, Sreepadaraj Karanam, Daniel J. Brunelle
AbstractPoly(butylene terephthalate) nanocomposites with organically modified montmorillonites have been prepared by in‐situ ring opening polymerization of PBT cyclic oligomers. High molecular weight polymers can be obtained by choosing the proper polymerization conditions and catalyst in very short polymerization time (10 min) and low temperature (205°C). A better dispersion of the clay and a con... hiện toàn bộ
Synthesis and characterization of poly(butylene terephthalate) nanocomposite fibers: Thermo‐mechanical properties and morphology
Wiley - Tập 100 Số 2 - Trang 1247-1254 - 2006
Jin‐Hae Chang, Mu Kyung Mun
AbstractNanocomposites of poly(butylene terephthalate) (PBT) with the organoclay C12PPh‐MMT were prepared using in situ intercalation polymerization. Hybrids with various organoclay contents were processed for fiber spinning to examine their thermal behavior, tensile mechanical properties, and morphologies for various draw ratios (DRs). The thermal properties (Tg, Tm, and TDi) of the hybrid fibers... hiện toàn bộ
Polymer latex particle size measurement through high speed dielectric spectroscopy
Wiley - Tập 39 Số 11-12 - Trang 2419-2441 - 1990
Bryan B. Sauer, Ruth S. Stock, Kyung‐Hee Lim, W. Harmon Ray
AbstractDielectric techniques have been implemented to study aqueous colloidal suspensions. A four electrode cell was used in two configurations; the first, a sweep of frequencies using a sequence of standard single frequency null‐balance measurements, and the second relying on the dielectric response to a Fourier synthesized pseudo random white noise (FSPN) with measurements performed using corre... hiện toàn bộ
Material extrusion‐based additive manufacturing of polypropylene: A review on how to improve dimensional inaccuracy and warpage
Wiley - Tập 137 Số 12 - 2020
Martin Spoerk, Clemens Holzer, Joamin González-Gutiérrez
ABSTRACTMaterial extrusion‐based additive manufacturing (ME‐AM) is an emerging processing technique that is characterized by the selective deposition of thermoplastic filaments in a layer‐by‐layer manner based on digital part models. Recently, it has attracted considerable attention, as this technique offers manifold benefits over conventional manufacturing technologies. However, to meet the chall... hiện toàn bộ
Coating of polyelectrolyte multilayer thin films on nanofibrous scaffolds to improve cell adhesion
Wiley - Tập 114 Số 3 - Trang 1574-1579 - 2009
Stephan Thierry Dubas, Paveenuch Kittitheeranun, Ratthapol Rangkupan, Neeracha Sanchavanakit, Pranut Potiyaraj
AbstractThe adhesion of L929 cells to poly(ϵ‐caprolactone) (PCL) nanofibers was successfully improved via coating with polyelectrolyte multilayer thin films (PEMs), which enhanced the potential of this material as a scaffold in tissue engineering applications. With the electrostatic self‐assembly technique, poly(diallyldimethylammonium chloride) (PDADMAC) and poly(sodium 4‐styrene sulfonate) (PSS)... hiện toàn bộ
Preparation of poly(acrylamide‐co‐acrylic acid)/silica nanocomposite microspheres and their performance as a plugging material for deep profile control
Wiley - Tập 134 Số 46 - 2017
Jingqi Ji, Chenlu Zeng, Yangchuan Ke, Yang Pei
ABSTRACTIn this work, poly(acrylamide‐co‐acrylic acid)/silica [poly(AM‐co‐AA)/SiO2] microspheres were prepared by inverse phase suspension polymerization in the presence of γ‐3‐(trimethoxysilyl) propyl methacrylate (or 3‐methacryloxypropyltrimethoxysilane) modified SiO2. The effects of SiO2 nanoparticles on tuning morphology and properties of the nanocomposite microspheres were studied. Plugging a... hiện toàn bộ
Epoxy–imide resins based on bis (carboxyphthalimide)s
Wiley - Tập 43 Số 4 - Trang 783-791 - 1991
K. Adhinarayanan, S. Packirisamy, Reena Susan George, V. Lakshmana Rao, R. Ramaswamy
AbstractEpoxy–imide resins have been obtained through the reaction of Araldite GY 250 (diglycidylether of bisphenol‐A and epichlorohydrin; difunctional) and Araldite EPN 1138 (Novolac‐epoxy resin; polyfunctional) with bis(carboxyphthalimide)s derived from 4,4′‐diaminodiphenylsulfone, 3,3′‐diaminodiphenylsulfone, 4,4′‐diaminodiphenylmethane and 4,4′‐diaminodiphenylmethane and trimellitic anhydride.... hiện toàn bộ
