“…Admicellar polymerization has been successfully used to coat thin polymer films on various kinds of substrates for several purposes. Examples are polystyrene on cotton,12 poly(methyl methacrylate) and polystyrene on aluminum,13 poly(tetrafluoroethylene) on alumina,14 poly(methyl methacrylate) on cellulosic fibers15 and polyester fabric,16 and polystyrene on glass fibers 17. In this research work, a phosphorus‐containing acrylic monomer was coated onto cotton surface by admicellar polymerization using an anionic surfactant.…”

The phosphorus-containing acrylate monomer, 2-acryloyloxyethyl diethyl phosphate (ADEP), was synthesized and applied to cotton fabric by using admicellar polymerization. Sodium dodecylbenzene sulfonate was used as the anionic surfactant. The film of polymerized monomer (PADEP) formed on the cotton surface was characterized by FTIR-ATR spectroscopy and SEM. Thermal and flame retardant properties of PADEP-coated cotton were investigated by TGA and flammability tests. Results showed that PADEP polymer film was successfully formed on the cotton fabric. The TGA and DTG analyses showed that the phosphorus-containing PADEP lowered the decomposition temperature of the treated fabric resulting in a higher char yield than in the case of untreated cotton. The flammability tests showed that the treated cotton had much improved flame retardancy property after the treatment. The treated fabric also retained its good pliability and soft touch with good air permeability.

“…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.

“…This technique has been widely studied in many systems. Thin films of polystyrene,16 poly(pyrrole),17 poly(2,2,2‐trifluoroethyl acrylate),18 and poly(styrene‐ isoprene)19 have been successfully formed on various substrates such as alumina,16 glass fiber,19 and mica 17. More recently, admicellar polymerization has been used to applied various types of polymer thin film on textile fabrics to produce fabrics with wider applications 20–23.…”

Two monomers with complimentary ultraviolet absorbing moieties, 2-[3-(2H-benzotriazol-2-yl)-4-hydroxyphenyl]ethyl methacrylate (BEM) and 2-hydroxy-4-acryloyloxybenzo phenone (HAB), were copolymerized through admicellar polymerization on a cotton fabric surface in order to improve its ultraviolet protection with broad spectral coverage. Separate and combined adsolubilization of the two monomers in dodecylbenzenesulfonate admicelles were studied and compared. Copolymer composition and monomer reactivity ratio were investigated by FTIR using Fineman-Ross and Kelen-Tü dos methods and it was found that the BEM-HAB copolymer system showed an alternating tendency and exhibited azeotropic polymerization at a particular composition. The copolymerization method used in this study provided a cotton fabric with uniform and complete UV-protection in the most hazardous regions. Ultraviolet protection factor (UPF) of the modified cotton was studied with a range of copolymer compositions and it was found that the fabrics coated by copolymer had higher values of UPF than homopolymers, while the monomer ratio of 1 : 1 gave the highest UPF value.
