Synthesis of Nanometer-Scale Polymeric Structures on Surfaces from Template Assisted Admicellar Polymerization: A Comparative Study with Protein Adsorption

A novel method for the formation of nanometer-scale polymer structures via template assisted admicellar polymerization (TAAP) is described. Admicellar polymerization uses a surfactant layer adsorbed on a surface to localize monomer to the surface prior to polymerization of the monomer. Nanostructures are formed by restricting adsorption to the uncovered sites of an already-templated surface, in this case to the interstitial sites between adsorbed latex spheres. Unlike most other process that form polymer nanostructures, polymer dimensions can be significantly smaller than the interstitial size because of sphere-surfactant interactions. Protein adsorption in the interstitial sites of colloidal arrays was also studied for three different proteins, and the results were compared with those obtained via admicellar polymerization.

“…It was observed that the bulky molecule of HAB led to a decrease in the adsorption of the surfactant. A decrease in the surfactant adsorption due to monomer adsolubilization is not an uncommon affair and has been reported earlier . HAB absorbs UV radiation very efficiently and gives absorption peaks at 270 and 330 nm.…”

There is no absorption in the visible range (400-700), hence one can be assured that it will not affect the color of any dyed fabric.…”

This article is an overview of a novel polymerization technique known as admicellar polymerization (ADPM).ADPM is known as a "surface analogue" of emulsion polymerization, and it consists of three main steps that include (1) admicelle formation, (2) adsolubilization, and (3) polymerization. This review encompasses all the applications of ADPM in the field of textiles. ADPM has been used mainly for finishing of textiles, e.g., for achieving flame retardancy, UV protection, water repellency, etc. It has also been used for improving the adhesion of natural fibers used for the reinforcement of polymer matrices. It was observed that though an extensive and constructive research work has been conducted at laboratory level to understand ADPM process and explore its applications, its industrial acceptance in textiles has not been reported yet. Scope for further research has also been discussed in this review article. C 2015 Wiley Periodicals, Inc. Adv Polym Technol 2015, 0, 21556; View this article online at wileyonlinelibrary.com.

“…Since initial reports in the mid-1980s [1,2], the admicellar polymerization technique has proven to be an effective way to modify the surface characteristics of solid substrates for rubber reinforcement [3][4][5], corrosion control [6,7], the formation of conducting films [8][9][10][11][12], the modification of cotton fibers [13][14][15][16][17][18][19], and composite fillers [20,21]. Admicellar polymerization has been summarized as a four-step process: formation of adsorbed surfactant aggregates (admicelles), monomer solubilization into the admicelle (adsolubilization), polymerization, and partial removal of surfactant.…”

Although admicellar polymerization has been termed the surface analog of emulsion polymerization, previous reports utilizing free radical-initiated admicellar polymerization relied on high levels of the free radical initiator when compared to emulsion polymerization, likely due to the presence of oxygen in the reported admicellar polymerization systems. Admicellar polymerizations of styrene on the surface of precipitated silica initiated by either a water-soluble or a water-insoluble initiator were studied to determine the effect of dissolved oxygen and free radical initiator solubility on the kinetics, yield, and molecular weight of the polymer formed. Results show that the presence of oxygen reduces the polymer yield and limits molecular weight. The solubility of the initiator also affected the polymer formed in the admicellar polymerization of styrene. While monomer conversions and polymer yield were similar, the molecular weights of polymerizations initiated by a water-soluble initiator were higher than comparable polymerizations initiated by a water-insoluble initiator.
