In this work, electrically conductive cellulose nanocrystals were used to reinforce shape memory polyurethanes, adding an extra variable to tune up the properties of these nanocomposites. The modified nanocrystals were prepared by an in situ polymerization method, growing polyaniline (PANI) on the surface of the cellulose nanofibrils [3]. These crystals combine the good mechanical properties of...

Dye-sensitized solar cell (DSSC) is a promising solution to global energy and environmental problems because of its clean, low-cost, high efficiency, good durability, and easy fabrication. However, enhancing the efficiency of the DSSC still is an important issue. Here we devise a bifacial DSSC based on a transparent polyaniline (PANI) counter electrode (CE). Owing to the sunlight irradiation si...

In the present work, a selective room temperature (RT) operable ammonia (NH3) sensor based on molybdenum disulphide (MoS2) nanosheet decorated with polyaniline (PANI) (MoS2-PANI) is successfully developed. The material prepared by simple chemical in-situ polymerisation of aniline. Prior to gas sensing studies, morphological, thermal and compositional studies are carried out. These reveal good i...

Citric-acid-modified polyaniline (P-CA) and P-CA modified with Ag nanoparticles (Ag@P-CA) were prepared via an in situ reduction method. The physicochemical properties of Ag@P-CA compared to unmodified (PANI) PANI-modified (Ag@PANI). had a lower content aniline oligomers Ag@PANI. greater monolayer adsorption capacity for 2-nitrophenol binding affinity as PANI Ag@PANI materials. X-ray photoelect...

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 infrared (ft-ir) spectroscopy and scanning electron microscopy (sem). the el...

determination of 1, 1-dimethylhydrazine (dmh) in air is carried out by spectrophotometry, gc or hplc analysis, but in this study dmh was analyzed by a gas sensor based on nanostructure conducting polyaniline. determination of dmh has been done very simplely and quickly in recent work. electrically conductive fibers have been prepared by polymerization of aniline on surfaces of commercial polyme...

Electrochemistry of PANI/Metal Composites in Basic Solutions

We report preparation of polyaniline (PANI) with radicals on the N-positions. Chirality of a PANI having optically active substituent is retained even upon oxidation by m-chloroperoxybenzoic acid in chloroform to generate spin species. Electron spin resonance and circular dichroism spectroscopy measurements suggest that the chiral paramagnetic properties of PANIs are derived from the combinatio...
