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...
فیلم کامپوزیت پلی آنیلین/گرافن کوانتوم دات/طلا (Au/PANI-GQD) از طریق فرآیند الکتروشیمیایی دو مرحله ای تهیه شد. در مرحله اول، مخلوط آنیلین و GQD حرارت داده، رفلاکس شده و بعد الکتروپلیمریزاسیون انجام شد. در مرحله دوم از طریق آبکاری الکتروشیمیایی، نانوذرات طلا بر روی سطح فیلم PANI-GQD ایجاد شد. ساختار الکترود PANI-GQD و Au/PANI-GQD توسط روبش میکروسکوپ الکترونی (SEM) و IR شناسایی شد. نتایج نشان داد...
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.
فیلم کامپوزیت پلی آنیلین/گرافن کوانتوم دات/طلا (au/pani-gqd) از طریق دو مرحله فرآیند الکتروشیمیایی تهیه شد. در اولین مرحله مخلوط آنیلین و gqd حرارت داده شد و سپس رفلاکس شده و بعد الکتروپلیمر شدن انجام داده شد. در مرحله دوم نانوذرات طلا در سطح فیلم pani-gqd توسط آبکاری الکتروشیمیایی kau(cn)2 پخش شد. ساختار الکترود pani-gqd و au/pani-gqd پوشش داده شده با طلا توسط میکروسکوپ روبش الکترونی (sem) و f...
The polyaniline (PANI) powder with globular sponge-like morphology was prepared by chemical solution polymerization, and its morphology and chemical structure were characterized by scanning electron microscope (SEM) and Fourier transform infrared spectroscopy (FTIR), respectively. The single electrode of electrochemical capacitor was made using the prepared PANI powder as active material and ca...
Nowadays, novel applications for polyaniline (PANI) make new demands on its morphology controlling, and designing novel PANI or PANI composite polymeric materials has been more and more attractive. In this work, octaaminophenyl polyhedral oligomeric silsesquioxane (POSS) was employed to prepare nanostructured PANI composites via controlled fabrication. By interfacial copolymerization, fibrous n...
A multi-hierarchical porous polyaniline (PANI) composite which could be used in good performance pressure sensor and adjustable sensitivity gas sensor has been fabricated by a facile in situ polymerization. Commercial grade sponge was utilized as a template scaffold to deposit PANI via in situ polymerization. With abundant interconnected pores throughout the whole structure, the sponge provided...
Polyaniline-NiFe2O4 nanocomposites (PANI-NiFe2O4) with different contents of NiFe2O4 (2.5, 5 and 50 wt%) were prepared via in situ chemical oxidation polymerization, while the nanoparticles nickel ferrite were synthesized by sol-gel method. The prepared samples were characterized using some techniques such as Fourier transforms infrared (FTIR), X-ray diffraction (XRD), scanning electron microsc...
Camphor sulfonic acid (CSA)-doped polyamide 6/polyaniline (PA6/PANI) composite nanofibers were fabricated using in situ polymerization of aniline under different CSA concentrations (0.02, 0.04, 0.06, 0.08 and 0.10 M) with electrospun PA6 nanofibers as templates. The structural, morphological and ammonia sensing properties of the prepared composite nanofibers were studied using scanning electron...
Improving the solubility of conductive polymers to facilitate processing usually decreases their conductivity, and they suffer from poor cycling stability due to swelling-shrinking during charging cycles. We circumvent these problems with a novel preparation method for nitrogen-doped graphene (NG) enhanced polyacrylic acid/polyaniline (NG-PAA/PANI) composites, ensuring excellent processibility ...
