AbstractPoloxamer hydrogels were prepared by photopolymerization from poloxamer macromer, which was synthesized by reaction of poloxamer 407 with acryloyl chloride. The synthesis of poloxamer macromer was confirmed using NMR and FTIR spectrometry. The gelation behavior and crystalline structure of poloxamer macromer was similar to those of poloxamer 407 itself; how...... hiện toàn bộ
Service lifetime prediction of nitrile butadiene rubber gaskets used in plate heat exchangersWiley - Tập 139 Số 28 - 2022

AbstractGasketed plate heat exchangers are characterized in a usual heat exchanger class. These systems employ elastomeric gaskets as the sealing element. Several conditions lead to oxidation and deterioration of these materials and their properties. In addition, the complex geometry of the gaskets and operation conditions may cause divergence in the expected aging...... hiện toàn bộ
Preparation and properties of a salt‐resistant superabsorbent polymerWiley - Tập 93 Số 6 - Trang 2532-2541 - 2004

AbstractCrosslinked sodium polyacrylate was prepared by solution polymerization with N,N‐methylene‐bisacrylamide (bisAM) as crosslinking agent; it was subsequently surface‐crosslinked by ethylene glycol diglycidyl ether (EGDE) and then was modified with inorganic salt to obtain a superabsorbent with water absorb...... hiện toàn bộ
Preparation and characterization of nylon610/functionalized multiwalled carbon nanotubes compositesWiley - Tập 113 Số 5 - Trang 2805-2812 - 2009
Zhongyuan Li, Shuzhen Xu, Wentao Liu, Suqin He, Chengshen Zhu
AbstractNylon610 nanocomposites containing functionalized multiwalled carbon nanotubes (MWCNTs) were prepared using wet melt blending method, which is a novel preparation technique. In comparison with the pure nylon610, the elastic modulus, tensile strength, bending modulus, and bending strength of the composites increase significantly with the increase of MWCNTs c...... hiện toàn bộ
Preparation and characterization of microcellular foamed thermoplastic polyamide elastomer composite consisting of EVA/TPAE1012Wiley - Tập 138 Số 37 - 2021

AbstractThermoplastic polyamide elastomer (TPAE) is a kind of high‐performance elastomers prepared from nylon hard segments and polyether or polyester soft segments. The hard segments endow TPAE with excellent mechanical properties, while the soft segments provide the desired elasticity. Therefore, the development of TPAE as a high‐performance foam material has bro...... hiện toàn bộ
