Abstract: Soil-bentonite slurry-trench wall, usually consisting of sandy soil and Na-bentonite, is used extensively as in-situ engineered barriers for contaminant containment. Clayey soil/Ca-bentonite may be considered as an alternative backfill when Na-bentonite is scarce at some sites. Adding trace amount of phosphate dispersant to clayey soil/Ca-bentonite backfills may be advantageous to ma…

Phase separation and crystallization in double crystalline symmetric binary p…
Abstract: Blending of two or more pure polymers is an effective way to produce composites with tunable properties. In this paper, we report dynamic Monte Carlo simulation results on the crystallization of crystalline/crystalline (A/B) symmetric binary polymer blend, wherein the melting temperature of A-polymer is higher than B-polymer. We study the effect of segregation strength (arises from …

New understanding for the formation of conductive network in the nanocomposit…
Abstract: Crystallization behavior of conductive composite has a great effect on the formation of conductive network. But very few studies have exposited, specially on the micro level, the evolution of conductive network during the crystallization of matrix. In this study, the conductive network was found to be destroyed by crystallization behavior of isotactic polypropylene (iPP) matrix, and…

Modified rubber seed oil based polyurethane foams
Abstract: In this work, rubber seed oil (RSO) was extracted with cyclohexane at room temperature for 24 h. The yield of RSO was about 40 %. The RSO was purified by using sodium hydroxide to eliminate some free fatty acids. Then the RSO was modified by simultaneous epoxidation and hydroxylation. Hydroxylated RSO (HRSO) had the hydroxylation extents 120 and 230 mgKOH/g with 2 h and 4 h reaction…

Ion-stimuli responsive dimethylaminoethyl methacrylate/hydroxyethyl methacryl…
Abstract: Novel ion-stimulus-responsive copolymeric hydrogels were synthesized by free radical crosslinking copolymerization from the monomers N,N-dimethylaminoethyl methacrylate (DMAEMA) and 2-Hydroxyethyl methacrylate (HEMA) in the presence of a crosslinker, diethyleneglycol dimethacrylate (DEGDMA). The influences of the reaction parameters, the comonomer composition and the ionic strength o…

Investigation of organic solvent/oil sorption capabilities of phenylene-bridg…
Abstract: Phenylene-bridged cross-linked poly(alkoxysilane)s produced by the condensation of 1,4-bis(triethoxysilyl) benzene (BTEB) with different lengths of aliphatic diols in proper stoichiometric ratios were successfully prepared. The synthesized phenylene-bridged poly(alkoxysilane)s were characterized by Fourier transform infrared spectroscopy (FTIR), solid-state 13C and 29Si cross polariz…

High-density polyethylene/halloysite nanocomposites: morphology and rheologic…
Abstract: The paper describes the preparation of High Density Polyethylene [HDPE]/Halloysite Nanotube [HNT] nanocomposites by melt compounding HDPE with varying amounts ofHNTs (ranging from 1 to 10%w/w) in the absence and presence of MA-g-HDPE as compatibiliser using corotating twin screw extruder. The effect of HNT loading and compatibiliser amount on morphology and rheological properties was…

High molecular weight poly(p-arylene sulfide ketone): synthesis and membrane-…
Abstract: High-molecular-weight poly(p-arylene sulfide ketone) (PPSK) was prepared by nucleophilic substitution reaction of 4,4’-diflurobenzophenone (DFBP) and sodium sulfide in the compound solvents of diphenyl sulfone (DPS) and 1,3- dimethyl-2-imidazolidinone (DMI) with catalysts under elevated temperature. The inherent viscosity (ηint) of the PPSK synthesized was 0.703 dl/g. PPSK was cha…
