In this work we propose randomly ordered polydomain nematic liquid crystal polymer networks to reversibly generate notable jagged relief patterns at a polymer coating surface by light illumination. The domain size is controlled by the addition of traces of partly insoluble fluorinated acrylate. The photoresponse of the coating is induced by a small amount of copolymerized azobenzene monomers. U...

Thermal spray in general, plasma spray in particular, is a highly complex process with numerous interacting variables associated with generation of the spray stream, deposit formation dynamics, and the resultant property linkages. Compounding this variability further are both the spatial (different booths and different locations) and temporal (process start-stops, hardware degradation, operator...

composite electrodes of polyaniline/mno2-multi walled carbon nanotube (pani/mno2-mwcnt), mno2-mwcnt nanocomposites and mwcnt was produced by the in situ direct coating approach. the supercapacitor performance of the nanocomposites was studied by fourier transform infrared (ft-ir) spectroscopy and scanning electron microscopy (sem). the electrochemical properties of electrodes were also investig...

Homogeneous surface coating of long carbon nanotubes is achieved by in situ polymerization of ethylene as catalyzed directly from the nanotube surface-treated by a highly active metallocene-based complex and allows for the break-up of the native nanotube bundles leading, upon further melt blending with HDPE, to high-performance polyolefinic nanocomposites.

The supercapacitive behavior of polyaniline/MnO2-carbon black (PANI/MnO2-CB), MnO2-CB nanocompositesand CB was studied. MnO2-CB made by the in situ direct coating method to deposit MnO2 onto CB; then PANI coating was coated on it. Morphology of the nanocomposite was studied by X-ray diffraction (XRD), Fourier transform...

An in-depth understanding of Na2Ti3O7 as a Na-ion battery anode is reported. The battery performance is enhanced by carbon coating, due to increased electronic conductivity and reduced solid electrolyte interphase formation. Ti(4+) reduction upon discharge is demonstrated using in situ XAS. The self-relaxation behaviour of the fully intercalated phase is revealed.

We developed a method for the in situ synthesis of an oligoamide coating on gold. The resultant surface chemical composition, wettability, and chemical nature were comparable to aromatic polyamide films used as reverse osmosis membranes. Hence, the oligoamide wafer may be used in adsorption/fouling studies as a surface mimetic of reverse osmosis membranes.

Organic-inorganic nanohybrids have been synthesized by in situ coating supramolecular nanotubular J-aggregates with helically wound silica ribbons, reflecting the J-aggregates' superstructure. The J-aggregates retain their morphology and optical properties in the nanohybrids, and display improved stability against elevated temperatures, chemical ambient and photo-bleaching.
