Summary of "Corrosion resistance mechanism of itaconic acid doped polyaniline /nano-graphene oxide composite coating."

Graphene Oxide (GO) and polyaniline (PANI) are very unique material with a broad potential in corrosion protection coating. To achieve maximum stability and anti-corrosion effect in polar medium, firstly itaconic acid doped PANI (DP) was readily prepared by one-step method, followed by forming GO and DP composite (GODP). Characterization by Fourier Transform Infrared Spectroscopy (FTIR) and UV-vis absorption spectra (UV-vis) provides evidence for the successful doping of itaconic acid in PANI. X-ray diffraction (XRD) analysis shows that the d-spacing of the GO sheets increases slightly with the intercalation of DP. The morphological studies show disordered structures in GODP compared with original GO sheets due to the introduction of PANI molecules and the interaction of functional groups on the surface of GO sheets. Thermogravimetric analysis (TGA) reveals good thermal stability of DP and GODP. Quantum calculation further confirms the successful doping of itaconic acid, and the effective complex of GO and DP, providing a quantitative understanding for the curing mechanism. The crosslinking interaction among GODP, curing agent, and epoxy resin facilitates the formation of compact coating, leading to excellent corrosion resistance towards Mg alloy.

Medical and Biotech [MESH] Definitions

A sequence-related subfamily of ATP-BINDING CASSETTE TRANSPORTERS that actively transport organic substrates. Although considered organic anion transporters, a subset of proteins in this family have also been shown to convey drug resistance to neutral organic drugs. Their cellular function may have clinical significance for CHEMOTHERAPY in that they transport a variety of ANTINEOPLASTIC AGENTS. Overexpression of proteins in this class by NEOPLASMS is considered a possible mechanism in the development of multidrug resistance (DRUG RESISTANCE, MULTIPLE). Although similar in function to P-GLYCOPROTEINS, the proteins in this class share little sequence homology to the p-glycoprotein family of proteins.

An integrated nano-scale approach to MEDICINE which involves concurrent diagnosis, drug delivery, therapy, and monitoring of therapeutic response.

A strain of Staphylococcus aureus that is non-susceptible to the action of METHICILLIN. The mechanism of resistance usually involves modification of normal or the presence of acquired PENICILLIN BINDING PROTEINS.

A type of strength-building exercise program that requires the body muscle to exert a force against some form of resistance, such as weight, stretch bands, water, or immovable objects. Resistance exercise is a combination of static and dynamic contractions involving shortening and lengthening of skeletal muscles.

The gradual destruction of a metal or alloy due to oxidation or action of a chemical agent. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed)
