Humidity-independent conducting polyaniline films synthesized using advanced atmospheric pressure plasma polymerization with in-situ iodine doping

Abstract: This study reports on the synthesis and characterization of conducting polyaniline (PANI) thin films when using advanced atmospheric pressure plasma jets (APPJs). A simple method for synthesizing conducting polymers (CPs) with humidity-independent characteristics is introduced using advanced APPJs and an in-situ iodine doping method. In the case of ex-situ I 2 doping, a humidity effect study showed that increasing the relative humidity produced significant changes in the electrical resistance (R) of the PANI, … Show more

“…The corresponding resistance was saturated at about 1.0 × 10 3 Ω after 20 min. In most polymer materials, the presence of water in or on the polymer structure changes the resistance and conductivity [ 15 , 16 , 17 , 18 ]. In polymer display applications, however, the I 2 -doped PANI film would be encapsulated by sealing materials to prevent access by moisture and oxygen, thereby protecting the resistance and conductivity [ 38 , 39 , 40 ].…”

“…Use of such system, however, is costly and requires routine maintenance, thereby limiting its application to batch processes. Therefore, an attractive alternative is the use of atmospheric pressure plasma (APP) polymerization for the synthesis of novel thin film materials [ 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 ]. With various advantages, including a low-temperature dry process and low-cost routine maintenance, APP polymerization is a promising growth system for the deposition of novel plasma polymer thin films with functional features that are well-suited for a wide range of applications and substrates.…”

“…Recently, various applications using organic nanoparticles have been intensively studied [ 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 ]. In particular, polyaniline (PANI) has attracted a significant attention because it is applicable to various promising electronic devices such as supercapacitors, sensors, corrosion protective layers, and flexible displays due to such good features as good environmental and high chemical stability, thermal stability, low cost, and easy synthesis [ 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 ]. In general, since a strong DC spark discharge is formed in the conventional SPP, it is difficult to synthesize organic nanoparticles requiring low temperature discharge.…”
