Pyrrole-aniline copolymers (poly(Py-co-Ani)) were synthesized using both three chemical, electrochemical and plasma polymerization methods. Comparison of the with methods was investigated. Fourier transform infrared spectroscopy (FT-IR), thermogravymetric analysis (TG-DTA), scanning electron microscopy (SEM) conductivity results confirmed that poly(Py-co-Ani) successfully obtained in all cases ...

During past few years, ionic liquids have kept attracting much attention as “green and designer” media for chemical reactions. Room-temperature ionic liquids have emerged as a potential replacement for organic solvents in catalytic processes on both laboratory and industrial scales (Holbrey & Seddon, 1999b). Literature reports on a wide range of reactions including advances in alkylation reacti...

The polymerization of vinyl monomers with cleavable enzymatic substrates has been shown to lead to water-soluble double-hydrophilic block copolymers which, upon enzymatic activation of the diblock copolymers, become amphiphilic and undergo self-assembly into colloidal nanostructures. The ability to change the chemical and physical characteristics of polymeric materials by an enzymatic reaction ...

This chapter describes the details of the synthesis of polyaniline (PAni) nanofiber reinforced polyvinyl alcohol (PVA) nanocomposites employing in-situ rapid mixing polymerization technique and the effect of SHI irradiation on the physico-chemical properties of the nanocomposites. Modifications in the morphology, conformation and the charge transport properties of the nanocomposites have been i...

We numerically investigate cooperative polymerization in an off-lattice model based on a pairwise additive potential using particles with a single attractive patch that covers 30% of the colloid surface. Upon cooling, these particles self-assemble into small clusters which, below a density-dependent temperature, spontaneously reorganize into long straight tubes. We evaluate the partition functi...

The polymerization of elongated micellar structures offers a novel approach to the production of high-aspect-ratio, water-soluble amphiphilic nanorods. A cationic surfactant with a vinyl-containing counterion, cetyltrimethylammonium 4-vinylbenzoate, has been synthesized and polymerized to produce high-aspect-ratio nanoparticles which are insensitive to changes in solution conditions. Aggregates...

Bulk quantities of electrically conducting nanotubes of polypyrrole having narrow pore diameter (6 nm) can be synthesized rapidly by chemical oxidative polymerization of pyrrole in the presence of stoichiometric amounts of V2O5 nanofibers. The V2O5 nanofibers act as templates for polymerization and yield, as the initial product, polypyrrole nanotubes with pores filled with V2O5. The V2O5 dissol...

Controlling chemical reactions within a small space is a significant issue in chemistry, and methods to induce reactions within a desired position have various potential applications. Here we demonstrate localized, efficient photopolymerization by radiation pressure. We induced a one-photon UV polymerization of liquid acrylate solutions in the optical-trapping potential of a focused near-IR (NI...

Quinolin-6-yloxyacetamides (QAs) are a chemical class of tubulin polymerization inhibitors that were initially identified as fungicides. Here, we report that QAs are potent anti-proliferative agents against human cancer cells including ones that are drug-resistant. QAs act by disrupting the microtubule cytoskeleton and by causing severe mitotic defects. We further demonstrate that QAs inhibit t...
