This work explains the functionalization of polyallylamine (PAA) on graphene oxide (GO) sheets following a chemical route. The resulting GO-PAA complex is characterized by using various imaging and analytical tools. In Raman spectroscopy for both GO GO-PAA, appearance D G characteristic bands correspond to sp2 sp3 contents, respectively, in carbon sheets. observation lowered D/G peak intensity ...

Abstract Among the high-performance and engineering polymers, polyimides closely related polyetherimide (PEI) stand out by their capability to react with nucleophiles under relatively mild conditions. By targeting phthalimide groups in chain backbone, post-functionalization offers a pathway adjust surface properties such as hydrophilicity, solvent resistance, porosity. Here, we use ultrathin PE...

The current paper provides an overview to emphasize the role of functionalization of multiwalled carbon nanotubes (MWCNTs) in manipulating cure kinetics of epoxy nanocomposites, which itself determines ultimate properties of the resulting compound. In this regard, the most commonly used functionalization schemes, that is, carboxylation and amidation, are thoroughly surveyed to highlight the rol...

Flexible, charged Pd nanosheets were prepared by using short chain thiolated carboxylic acids and amines. They could wrap around amine or hydroxyl functionalized micron-sized spheres driven by electrostatic interactions. Upon incubation with HepG2 cells, the positively charged cysteamine (CA) functionalized Pd nanosheets exhibited a much higher cytotoxicity, showing more than 80% cell death at ...

We report the development of a novel method for functionalizing polymerized crystalline colloidal arrays (PCCA). This new method enables us to easily incorporate molecular recognition agents into the PCCA to produce chemical sensing materials that report on analyte concentration via diffraction of visible light. We copolymerize glycidyl methacrylate with acrylamide and N,N′-methylenebisacrylami...
