We have prepared different hybrid polymer-phthalocyanine materials by solution processing, starting from two sulfonated phthalocyanines, s-CoPc and CuTsPc, and polyvinylpyrrolidone (PVP), polyethylene glycol (PEG), poly(acrylic acid-co-acrylamide) (PAA-AM), poly(diallyldimethylammonium chloride) (PDDA) and polyaniline (PANI) as polymers. We also studied the response to ammonia (NH3) of resistor...

We report about the first Raman spectroscopy study of a vesicle-assisted enzyme-catalyzed oligomerization reaction. The aniline dimer N-phenyl-1,4-phenylenediamine (= p-aminodiphenylamine, PADPA) was oxidized and oligomerized with Trametes versicolor laccase and dissolved O2 in the presence of sodium bis(2-ethylhexyl)sulfosuccinate (AOT) vesicles (80-100 nm diameter) as templates. The conversio...

Polyaniline-functionalized graphene quantum dots (PANI-GQD) and pristine graphene quantum dots (GQDs) were utilized for optoelectronic devices. The PANI-GQD based photodetector exhibited higher responsivity which is about an order of magnitude at 405 nm and 7 folds at 532 nm as compared to GQD-based photodetectors. The improved photoresponse is attributed to the enhanced interconnection of GQD ...

We fabricated hydrogenated amorphous silicon/polyaniline n–i–p heterojunction solar cells incorporating a doped, hole conducting polyaniline (PANI) layer. The cells were prepared by spin-casting differing polyaniline dispersions corresponding to film conductivities ranging from 10 2 to 10 S/m. The open-circuit voltages VOC of the cells ranged from 0.5–0.7 V. While these open-circuit voltages ar...

Monodisperse polystyrene (PS) seed latex was initially prepared by a dispersion polymerization, and then polyaniline (PANI)-coated PS composite particles were synthesized by diffusion and polymerization of aniline at the interface. Characteristics of the obtained PS/PANI composite particles such as morphology and thermal property were examined using SEM and TGA, respectively. In addition, we em...

In this work, nanoflower-like MoS2 grown on the surface of multi-walled carbon nanotubes (MWCNTs)/polyaniline (PANI) nano-stem is synthesized via a facile in situ polymerization and hydrothermal method. Such a novel hierarchical structure commendably promotes the contact of PANI and electrolyte for faradaic energy storage. In the meanwhile, the double-layer capacitance of MoS2 is effectively us...

Composites of polyaniline and carbon nanotube (CNT) were prepared by in-situ chemical polymerization method using various aniline concentrations in the initial polymerization solution with p-toluene sulfonic acid (PTS) as secondary dopant and mechanical mixing of the PANI and CNT using different weight ratios of PANI and CNTs. The structural characterizations of the composites were done by Four...

A facile fabrication strategy via electrospinning and followed by in situ polymerization to fabricate a patterned, highly stretchable, and conductive polyaniline/poly(vinylidene fluoride) (PANI/PVDF) nanofibrous membrane is reported. Owing to the patterned structure, the nanofibrous PANI/PVDF strain sensor can detect a strain up to 110%, for comparison, which is 2.6 times higher than the common...

The morphological evolution of PANI helixes was achieved without the use of chiral dopants, but by a facile process through the generation of onion-like multi-lamellar vesicles used as a novel soft-template and a liquid crystal acting as a promoter for PANI polymerization and self-assembly, which is a breakthrough for the synthesis of helical structures.
