Precise Control of Charge-Structure Coupling in Polyamide Membranes for Mono- and Divalent Ion Separation. [PDF]

Adv Sci (Weinh)
A zwitterionic copolymer, Poly(2‐methacryloyloxyethyl phosphorylcholine‐co‐2‐aminoethyl methacrylate hydrochloride) (P(MPC‐co‐AEMA)) copolymers, with tunable MPC/AEMA ratios, is grafted onto the polyamide (PA) selective layer via secondary interfacial polymerization. Balancing reactive anchoring segments (AEMA) and zwitterionic segments (MPC) regulated

Superlubricity and Corrosion Inhibition Properties of Solvate Ionic Liquids in Hybrid Carbon Fiber Reinforced Plastic–Steel Interfaces

Advanced Engineering Materials, EarlyView.
Solvate ionic liquids lubrication reduced the coefficient of friction by ∼60% compared to dry sliding, reaching steady‐state values as low as 0.04–0.05. Corrosion weight‐loss measurements in 1 M HCl further demonstrated significant inhibition behavior, with only 100 ppm of [Li(G3)][TFSI] (∼68.5 μL/L) reducing corrosion‐product weight loss by 63 ...

Water sorption and solubility of polyamide denture base materials

Acta Biomaterialia Odontologica Scandinavica, 2017
Purpose: Some patients experience adverse reactions to poly(methyl methacrylate)-based (PMMA) dentures. Polyamide (PA) as an alternative to PMMA has, however, not been well documented with regard to water sorption and water solubility. The aim of this in

Effect of humidity on diameter of polyamide 6 nanofiber in electrospinning process

Mechanical Engineering Journal, 2016
Various thermoplastic polymers have been spun to nanofibers by the electrospinning method, in which a polymer solution is ejected as a fine jet of liquid from the tip of the needle and is deposited on the collector by applying a high voltage to the ...
