Transparent anti-fogging and self-cleaning coatings are of great interest for many applications, including solar panels, windshields displays or lenses to be used in humid environments. In this paper, we report on the simultaneous synthesis, at atmospheric pressure, anatase TiO2 nanoparticles low-temperature, high-rate deposition TiO2/SiO2 nanocomposite coatings. These exhibit durable super-hydrophilic photocatalytic properties. The strategy followed relies concomitant separated injections...
Abstract Modulating the interfacial charge alignments by molecular engineering in an organic heterojunction device is a smart strategy to improve its conductivity, which can be exploited high‐performance gas‐sensor development. Herein, fabrication of new devices based on porphyrin tapes and phthalocyanines their potentiality ammonia sensing at different relative humidity (rh) are investigated.

UV and visible light photocatalytic composite Pt Au-TiO2 coatings have been deposited on silicon glass substrates at low temperature using a hybrid ECWR-PECVD/MS-PVD process. Methylene blue, stearic acid, sulfamethoxazole were used as dye, organic, antibiotic model pollutants, respectively, to demonstrate the efficiency of these nanocomposite for water decontamination or self-cleaning surfaces applications. Raman investigations revealed formation anatase polymorph TiO2 in all synthesized...
Due to the undeniable industrial advantages of low-temperature atmospheric-pressure plasma processes, such as low cost, temperature, easy implementation, and in-line process capabilities, they have become most promising next-generation candidate system for replacing thermal chemical vapor deposition or wet processes functional coatings. In work detailed in this article, photocatalytic anatase TiO2 thin films were deposited at a temperature on polymer optical fibers using an process. This...
Metalloporphyrin-based photocatalysts have attracted great interest due to their high extinction coefficient in the visible range coupled a catalytically active central metal ion surrounded by highly conjugated heterocyclic macrocycle. In this work, fused copper(II) porphyrin-based polymer thin films are shown be electrocatalysts and for heterogeneous hydrogen evolution reaction (HER). The porphyrin notably show significant reduction of overpotential required HER comparison reference...
Abstract Oxidative polymerization of nickel(II) 5,15‐diphenyl porphyrin and 5,15‐bis(di‐3,5‐tert‐butylphenyl) by oxidative chemical vapor deposition (oCVD) yields multiply fused oligomers in thin film form. The oCVD technique enables one‐step formation, deposition, p‐doping conjugated poly(porphyrins) coatings without solvents or post‐treatments. decisive reactions side during the process are shown high‐resolution mass spectrometry. Owing to highly structure tapes, films exhibit an...
While the solution‐phase synthesis of directly fused porphyrin tapes has been successfully developed in recent years, deposition these promising compounds thin film form remained a challenge.

The straightforward synthesis of directly fused porphyrins (porphyrin tapes) from 5,15-diphenyl porphyrinato nickel(ii) complexes with different substituents on the phenyl rings is achieved while processing gas phase. porphyrin tapes, exhibiting NIR absorption, are readily obtained in thin film form. phase approach cuts need for solubilizing groups allowing first time study their conductivity according to substituent. 2-Point probe and AFM measurements evidence that reducing size meso...

Abstract Hydrophobic coatings based on dodecyl acrylate (DOCA) and perfluorodecyl (PFDA) have been generated via “postdischarge” atmospheric pressure plasma deposition. These exhibit a water contact angle (WCA) of around 125° but are accompanied by poor mechanical strength. To improve this property, two different types chemical crosslinkers, that is, hexanediol methacrylate (HDMA) diacrylate (HDA), incorporated into the precursor mixture. After polymerization, both with crosslinkers...
