Journal ArticleDOI
Functionalization of nanomaterials with aryldiazonium salts.
Ahmed A. Mohamed,Ahmed A. Mohamed,Zakaria Salmi,Si Amar Dahoumane,Ahmed Mekki,Benjamin Carbonnier,Mohamed M. Chehimi,Mohamed M. Chehimi +7 more
TL;DR: Aryldiazonium salts are highlighted as efficient coupling agents for many types of molecular, macromolecular and nanoparticulate species, therefore ensuring stability to colloids on the one hand, and the construction of composite materials and hybrid systems with robust and durable interfaces/interphases, on the other hand.
Journal ArticleDOI
H2S sensing using in situ photo-polymerized polyaniline–silver nanocomposite films on flexible substrates
Ahmed Mekki,Ahmed Mekki,Nirav Joshi,Ajay Singh,Ajay Singh,Zakaria Salmi,P. Jha,Philippe Decorse,Stéphanie Lau-Truong,Rachid Mahmoud,Mohamed M. Chehimi,Dinesh K. Aswal,Shiv K. Gupta +12 more
TL;DR: In this paper, the authors demonstrate the preparation of flexible polyaniline-silver (PANI-Ag) nanocomposite films via an in situ facile UV induced polymerization of aniline in presence of AgNO 3.
Journal ArticleDOI
Core/shell, protuberance-free multiwalled carbon nanotube/polyaniline nanocomposites via interfacial chemistry of aryl diazonium salts
Ahmed Mekki,Soumen Samanta,Ajay Singh,Ajay Singh,Zakaria Salmi,Rachid Mahmoud,Mohamed M. Chehimi,Dinesh K. Aswal +7 more
TL;DR: It was found that M WCNT-PANI nano-composites with higher MWCNTs loading yield PANI chains with more quinoid units than the pure PANI, which results in significant improvement in the conductivity of the composites.
Journal ArticleDOI
Quartz crystal microbalance VOCs sensor based on dip coated polyaniline emeraldine salt thin films
Zaher Ihdene,Ahmed Mekki,Ahmed Mekki,Boualem Mettai,Rachid Mahmoud,Boudjema Hamada,Mohamed M. Chehimi +6 more
TL;DR: In this paper, PANI-DBSA films were found to be highly sensitive (∼7-Hz/ppm), selective to para-xylene (over toluene and benzene) and have a limit of detection of 3-ppm.
Journal ArticleDOI
Exfoliated clay/polyaniline nanocomposites through tandem diazonium cation exchange reactions and in situ oxidative polymerization of aniline
Khouloud Jlassi,Khouloud Jlassi,Khouloud Jlassi,Ahmed Mekki,Ahmed Mekki,Mémia Benna-Zayani,Mémia Benna-Zayani,Ajay Singh,Dinesh K. Aswal,Mohamed M. Chehimi,Mohamed M. Chehimi +10 more
TL;DR: In this article, conductive clay/polyaniline nanocomposites were prepared through a simple approach which consists of in situ polymerizing aniline, in the presence of the 4-diphenylamine diazonium-modified bentonite.
