Abstract Aramid fibers have relatively low surface activity and poor UV resistance. Herein, this paper design a functionalized treatment method. Firstly, the aramid fibers are modified with NaOH and HCl solutions, then the fibers are functionalized with dopamine to improve the surface activity and enhance UV resistence properties. The morphology, chemical structure, the aggregation structure and UV resistance of aramid fibers were studied by scanning electron microscopy, infrared spectroscopy, X...

Abstract Porous polymer monoliths were prepared by emulsion templating. The relationship between emulsion behavior and cellular morphology and mechanical properties after polymerization of the monomeric continuous phase was investigated. Porous poly(High Internal Phase Emulsion)s were synthesized with the same strut material and relative density but different morphology and mechanical properties, achieved by varying the surfactant system and concentration. The range of morphologies spanned from ...

Abstract Defect–rich zinc sulfide (ZnS, ZS) was successfully synthesized by the slow release of S source from glutathione (GSH) to coordinate with Zn2+ at high temperature. Based on this, a novel ZnS/g–C3N4 (ZSCN) heterojunction with high catalytic activity was fabricated through facile in–situ hydrothermal method. The removal rates of Rhodamine B (RhB), methyl orange (MO), methylene blue (MB) and Cr6+ for ZSCN–0.05 with the highest catalytic activity under full–spectrum illumination were 13.0, ...

Abstract Herein, we describe the dynamics of gel transition of silica sol (tetraethoxysilane (TEOS) in ethanol-H2O to xerogel via oranogel route. Silica sol made in ethanolic solution turns into an organogel during sol-gel synthesis of TEOS, which eventually makes a phase transition to xerogel following a process of spontaneous dehydration of the gel network at room temperature. It was observed that the gelation time decreased with the increasing concentration of TEOS which was captured from dyn...

Abstract Magnetic crosslinked polystyrene (CPS) was prepared via a solvent-free surface-initiated atom transfer radical polymerization (ATRP) technique. Organically modified magnetite nanoparticles (MNP′s) were used as the polyaddition initiator. Also, an α,ω-bis-4-(vinylbenzyl)ether of polyoxyethylene (BVE) was utilized as the comonomer/crosslinker. In addition to Fe3O4-containing crosslinked polymer (donated with MNP′s@BVE-CPS), a non-magnetic polystyrene (denoted with BVE-CPS) was also prepar...

Abstract Polymer gel has been widely used as a plugging agent for blocking the thief zones and improving the oil production. However, the performance of conventional polymer gel is unsatisfactory in high salinity conditions because of its rapid syneresis. In this work, an amphiphilic polymer gel was formulated by crosslinking salt resistant amphiphilic polymer with organic chromium, which had very low syneresis under high salinity (NaCl 80,000 mg/L) and temperature (85 °C) conditions. Together w...

Abstract Aggregation as an essential mechanism impacting nanoparticle (NP) functionality, fate, and transport in the environment is currently modelled using population-balance equation (PBE) models which are computationally expensive when combined with other continuum-scale reactive transport models. We propose a new simple mass-concentration-based, chain-reaction modelling (CRM) framework to alleviate computational expenses of PBE and potentially to facilitate combination with other fate, trans...

Abstract In this paper, the thickness and stability of common black films (CBFs) in two ionic–nonionic mixed surfactant systems were compared based on the phase diagram of the adsorbed film. The mixed surfactant systems examined were (1) cetyltrimethylammonium chloride (CTAC) – n-dodecyl-β-D-maltoside (β-C12G2) and (2) lithium perfluorooctanesulfonate (LiFOS) – tetraethyleneglycolmonooctyl ether (C8E4) systems. When the attraction between the two surfactants in the adsorbed film was weak, the fo...

Abstract Synthesis, characterization, and in-vitro/in-vivo examinations of a theranostic system with novel formulation and straightforward synthesis method are reported in this work. Deferrioxamine-manganese(II), as a theranostic complex (Deferrioxamine as therapeutic and manganese(II) as MRI imaging agent) is conjugated in adjacent to folic acid with the PEGylated gold nanoparticles, leading to formation of biodegradable and biocompatible AuNPs-PEG-[DFO-Mn(II)]‖-[FOA] system. The fabrication pr...

Abstract The current study focused on the preparation of adsorptive nanocomposite membrane for Cu(II) removal from aqueous solution. TiO2 nanoparticles as adsorbent and Polyaniline (PANi) as a modifier to improve dispersion quality and adsorption capacity of TiO2, were added to the polyethersulfone (PES) casting solution. Adsorptive membranes were prepared at different dosage of PANi-TiO2 nanocomposite (3, 5 and 7 wt.%). The as-prepared membranes were characterized with respect to chemical struc...
