Polypyrrole (PPy) was synthesized using the Chemical polymerization technique Ammonium per sulphate (APS), as an oxidant and Plasma Polymerization technique. The polypyrrole by chemical oxidation method in black amorphous powder form. In polymerization, thin films were created on a glass plate. Structural morphological properties of polymer studied FTIR, SEM and. X-ray diffraction. electrical c...

Hybrid nanocomposites of binary Pt-Ru/Polyaniline were prepared by oxidative polymerization of aniline andformation Pt and Ru nanoparticles. The polymerization of aniline was carried out in the presence of Potassiumhexa cyano Platinate (IV) and Ruthenium (III) nitrosyl nitrate as oxidizing agents. During the reaction anilinemonomers undergo oxidation and form polyaniline (PANi) whereas the redu...

Thiol oxidation is a probable outcome of cellular oxidative stress and is linked to degenerative disease progression. In addition, protein thiol redox reactions are increasingly identified as a mechanism to regulate protein structure and function. We assessed the effect of hypothiocyanous acid on the cytoskeletal protein tubulin. Total cysteine oxidation by hypothiocyanous and hypochlorous acid...

Paracetamol was polymerized in a reaction mixture containing xanthine oxidase, xanthine and paracetamol. This polymerization reaction was not inhibited by allopurinol or KCN, indicating that neither the molybdenum sites nor the iron-sulphur centres of the enzyme were involved in this catalytic activity. Removal of the flavin centres from the enzyme, however, completely abolished paracetamol oxi...

The major products of the initial steps of ferulic acid polymerization by lignin peroxidase included three dehydrodimers resulting from beta-5' and beta-beta'coupling and two trimers resulting from the addition of ferulic acid moieties to decarboxylated derivatives of beta-O-4'- and beta-5'-coupled dehydrodimers. This is the first time that trimers have been identified from peroxidase-catalyzed...

High surface area porous conjugated polymers were synthesized via the high internal phase emulsion polymerization technique and micropore engineering as efficient heterogeneous photocatalysts for highly selective oxidation of organic sulfides to sulfoxides under visible light.

Core/shell nanomaterials composed of only polypyrroles (PPys) were fabricated by microemulsion polymerization using two oxidants with different chemical oxidation potentials, and used as a precursor for the fabrication of PPy and carbon nanocapsules.

We highlight the role of thiyl initiating radicals generated by air oxidation thiols in mechanism accounting for self-initiation thiol–ene polymerization. The driving force this reaction is polarization S–H bond.

Polymers can be prepared using chemical and/or electrochemical methods of polymerization (see Chap. 2), although most redox polymers have been synthesized by chemical polymerization. Electrochemically active groups are either incorporated into the polymer structure inside the chain or included as a pendant group (prefunctionalized polymers), added to the polymer phase during polymerization, or ...

Silver-Polyaniline (Ag-PANI) nanocomposites were prepared by in-situ oxidative polymerization of aniline monomer in sodium bis(2-ethylhexyl) sulfosuccinate (AOT) solution as an emulsifier. The synthesis of Silver-Polyaniline nanocomposites was investigated as a function of several parameters such as aniline concentration, concentration of emulsifier (AOT), concentration of oxidation agent and c...
