Plasma-polymerized polyaniline films: Synthesis and characterization

Recent advances in hollow and core–shell intrinsically conducting polymers for applications in electromagnetic interference shielding/microwave absorption, removal of metal ions/dyes and supercapacitors

“…In addition, several other preparative methods for conducting polymers have been used, such as photopolymerization, 157 radio-frequency plasma polymerization, 158 organometallic cross-coupling reaction 159 and vacuum vapour phase polymerization. 160,161 The properties of the conducting polymers are influenced by oxidant, monomer molar ratio, type of oxidizing agent, pH, polymerization temperature, time, concentration, electrolyte concentration, and degree of doping.…”

Effect of Deposition Time on Electrochemical Properties of Polyaniline Samples Prepared by Chemical Bath Deposition

“…C-H vibrations in CH 2 are observed at 2862, 2854cm -1 [26] , and C=N stretching vibrations of the quinoid ring are observed at 1739cm -1 [26] . The peaks at 1571 and 1574 demonstrate the C=C stretching vibrations of the quinoid ring [29][30] , and at 1451 and 1571cm -1 , stretching vibrations of the benzene ring are observed. The peak at 1451cm -1 shows C-N + stretching vibrations [26] .…”

“…The peak at 1451cm -1 shows C-N + stretching vibrations [26] . The peak at 1301cm -1 shows C-N stretching vibrations of aromatic ring [31] , at 1206cm -1 shows stretching vibrations in an aromatic primary ring [27] , at 1100 and 1118cm -1 shows plane bending vibrations of aromatic C-H [29] , at 913cm -1 shows quinoid ring -NH + -benzoic ring stretching vibrations [26] , at 904cm -1 shows C-H out of the plane bending vibrations [28] , at 810cm -1 and 671cm -1 shows meta substitutions, 1,3 disubstitution in benzene ring [33] , at 713,501cm -1 shows ortho substitutions, 1,2 disubstitutions in benzene ring [30] , and at 608,603cm -1 vibrations in aryl nitro compounds are observed [29] . Therefore, it can be concluded that the samples obtained are PANI.…”

Nonthermal Atmospheric Plasmas in Dental Restoration

“…It has been long documented that plasma can induce polymerization by direct energy transfer (i.e., bombarding reactive species, including radicals, ions, and metastable species, to monomer) and indirect energy transfer (e.g., absorption of UV-visible emission by monomer; Epaillard et al 1989;Gong et al 1998;Çökeliler et al 2007). NTAP is believed to enhance polymerization via the same mechanisms.…”
