TL;DR: In this paper, an attempt was made to elucidate the mechanisms of formation in terms of interfacial turbulence between two unequilibrated liquid phases involving flow, diffusion and surface tension decrease (Marangoni effect).

TL;DR: Polyaniline nanofibers with uniform diameters between 30 and 50 nm can be made in bulk quantities through a facile aqueous/organic interfacial polymerization method at ambient conditions and have superior performance in both sensitivity and time response to vapors of acid and base.
Abstract: Polyaniline nanofibers with uniform diameters between 30 and 50 nm can be made in bulk quantities through a facile aqueous/organic interfacial polymerization method at ambient conditions. The nanofibers have lengths varying from 500 nm to several micrometers and form interconnected networks. Thin films made of the nanofibers have superior performance in both sensitivity and time response to vapors of acid (HCl) and base (NH3).

TL;DR: In this paper, a review of the preparation of polymer nanoparticles and the crucial parameters involved in techniques designed to obtain the desired properties is presented, and the choice of method depends on a number of factors, such as particle size, particle size distribution, area of application, etc.

TL;DR: Thin, crumpled polymer films on ceramic supports are high-flux membranes for removing small molecules from organic fluids and were sufficiently rigid that the crumpling textures could withstand pressurized filtration, resulting in increased permeable area.
Abstract: Membranes with unprecedented solvent permeance and high retention of dissolved solutes are needed to reduce the energy consumed by separations in organic liquids We used controlled interfacial polymerization to form free-standing polyamide nanofilms less than 10 nanometers in thickness, and incorporated them as separating layers in composite membranes Manipulation of nanofilm morphology by control of interfacial reaction conditions enabled the creation of smooth or crumpled textures; the nanofilms were sufficiently rigid that the crumpled textures could withstand pressurized filtration, resulting in increased permeable area Composite membranes comprising crumpled nanofilms on alumina supports provided high retention of solutes, with acetonitrile permeances up to 112 liters per square meter per hour per bar This is more than two orders of magnitude higher than permeances of commercially available membranes with equivalent solute retention

TL;DR: Interfacial polymerization is shown to be readily scalable to produce bulk quantities of nanofibers and the measured Brunauer-Emmett-Teller surface area of the nan ofibers increases as the average diameter decreases.
Abstract: Uniform polyaniline nanofibers readily form using interfacial polymerization without the need for templates or functional dopants. The average diameter of the nanofibers can be tuned from 30 nm using hydrochloric acid to 120 nm using perchloric acid as observed via both scanning and transmission electron microscopy. When camphorsulfonic acid is employed, 50 nm average diameter fibers form. The measured Brunauer-Emmett-Teller surface area of the nanofibers increases as the average diameter decreases. Further characterization including molecular weight, optical spectroscopy, and electrical conductivity are presented. Interfacial polymerization is shown to be readily scalable to produce bulk quantities of nanofibers.
