Morphological Investigation of Poly(2‐aminothiazole) Prepared by Rapid Initiated Polymerization

Abstract

The bulk and template-free method to synthesize poly(2-aminothiazole) (P2AT) and also morphological investigation by scanning electron microscopy are presented. The approach uses rapid initiated strategy by sodium hypochlorite as the oxidant and acetic acid, hydrochloric acid or camphorsulfonic acid as the dopant. Moreover, size controlling of P2AT nanoparticles was accomplished by employing different dopants, molar ratios of reactants, temperature and time, ranged from 20 to 380 nm in diameter. These nanoparticles can self-assemble into plate-like microstructures under certain conditions. According to the results, the amount of doping agent has a critical role in tailoring the nano-and microstructure of P2AT. The as-obtained P2AT with platelike microstructure containing nanoparticles exhibited fluorescence emission at 430 nm. According to the nitrogen adsorption isotherm, the P2AT has a porous structure as the surface area was determined to be 38.54 m 2 g À1 with the average pore size of 2.1 nm.

Chemical Oxidative Polymerization of 2-Aminothiazole in Aqueous Solution: Synthesis, Characterization and Kinetics Study

“…However, there are only a few studies on synthesis of PAT by chemical oxidative polymerization, which has an obvious advantage in production of polymers on a large scale. The chemical oxidative polymerization of AT has been conducted using different oxidant/solvent systems, including sodium hypochloride/acetic acid aqueous solution [16,17], CuCl 2 ·6H 2 O/1,4-dioxane [18], benzoyl peroxide/1,4-dioxane [19], and anhydrous FeCl 3 /nitromethane (CH 3 NO 2 ) at a low oxidant/monomer molar ratio (as low as 0.01) [20].…”

Electrospun poly(2‐aminothiazole)/cellulose acetate fiber membrane for removing Hg(II) from water

“…Poly(2‐aminothiazole) (PAT) is a novel conducting polymer based on 2‐aminothiazole (AT) monomer . AT‐based heavy metal ion adsorbents (e.g., AT‐modified SiO 2 gel and AT‐functionalized polystyrene) have been reported earlier, probably owing to the substantially higher S and N ratio (30 mol %) in AT compared with that in aniline (7 mol %) and pyrrole (10 mol %).…”
