Fabrication and characterization of polyaniline-based gas sensor by ultra-thin film technology

Synthesis and Characterization of Polyaniline Nanoparticle by Inverse Micelle Microemulsion Method

“…Moreover, organic polymer with conductive properties also attracts attention. Complement to these physical properties, the organic conductive polymer also gain attention for certain purposes, such as for solar cell [1], light emitting diode [2,3], conductive ink, sensor [4][5][6][7], semiconductor [8], super-capacitor [9], energy storage [10], catalysis and catalyst supporting material [11][12][13]. In our ongoing research finding non-metallic material catalyst for alpha-pinene oxidation [14][15][16] into more valuable chemicals, it turned up on polyaniline nanoparticle (PANI-NP) as prospectus catalyst.…”

“…Synthesis PANI under solution into a thin film [6] and nanoparticle with a low cost process can be achieved easily, while conductivity and catalytic activity can vary depend on the particle size [23][24][25], and form of the oxidation level on the both benzenoid and quinoid series structure [5,18,26,27]. Specific to the application of polyaniline as a catalyst for hydrocarbon oxidation, the decreasing of nanoparticle size from 80-100 nm to 10-20 nm improve its catalytic reactivity [12].…”

Polyvinylcarbazole films: Applications for chemical sensors

“…Among sensors based on organic materials, conductive polymers are the most common [1][2][3][4][5][6][7][8][9][10]. The advantages of these sensors are above all an opportunity to work at room temperature, easiness of manufacturing and low cost.…”

“…Polyaniline ultrathin layers were prepared using the LangmuirBlodgett method, and gas sensitivity of these films to NO was studied [2]. Using the Langmuir-Blodgett methods, thin layers of pure polycarbazole and polycarbazole mixed with octadecylamine were obtained.…”

Dispositivos flexíveis de monitoramento de pH e de deflexão mecânica à base de polianilina

“…Atualmente, diodos, transistores, sensores de gases, sensores químicos e biológicos, dosímetros, aplicações em eletrônica biomolecular, músculos artificiais, diodos emissores de luz, displays luminosos, células fotovoltaicas são outros exemplos de aplicações dos polímeros eletrônicos [5][6][7][8][9][10][11] . Nesse contexto, o estudo e a caracterização de filmes e sistemas orgânicos à base de polianilina (PAni) para aplicações em dispositivos eletrônicos têm despertado grande interesse tecnológico [12,13] . Isso ocorre pelo fato desse polímero apresentar, além da possibilidade de controle da sua condutividade elétrica por meio da exposição a soluções ácidas ou básicas, baixos custos de produção, solubilidade em diversos solventes orgânicos, facilidades de processamento e de manufatura na forma de filmes finos e, finalmente, estabilidades térmica, química e elétrica [14] .…”
