Infrared and ultra violet-visible spectroscopic investigation of plasma polymerized N,N,3,5-tetramethylaniline thin films

Space charge limited conduction in plasma polymerized N,N,3,5 tetramethylaniline thin films

“…They predicted that the substitution of electron donor groups like -N(CH 3 ) 2 in aniline might effect the electronic property. Plasma polymerized N,N,3,5 tetramethylaniline (PPTMA) thin films have been prepared by using a capacitively coupled reactor and the results of infrared (IR) and ultraviolet -visible spectroscopic investigation have been reported [18]. It is seen that PPTMA thin film with conjugation can be produced by plasma polymerization and the structural order can be improved by heat treatment.…”

Electrical and optical properties of plasma-polymerizedN,N,3,5-tetramethylaniline thin films

“…More details of IR studies about TMA and PPTMA thin films have been reported in a previous article [20]. The absorption peaks in the PPTMA thin films are not sharp compared to those of the TMA but most of the IR absorption features of the TMA are noticeable in the spectrum of PPTMA thin films with shifts in wave numbers.…”

“…Details about the plasma polymerization system used in this work have been discussed in an earlier publication [20]. Glow discharge plasma was generated around the substrates, which were kept on the lower electrode, using a step up transformer connected to the electrodes with a power of about 40 W at line frequency (50 Hz) at a chamber pressure of about 1 × 10 −1 Torr.…”

“…Thus, these films may be a probable candidate for low dielectric constant applications. The chemical analysis by IR spectroscopy and UV-vis spectroscopy of plasmapolymerized N,N,3,5-tetramethylaniline (PPTMA) thin films have been reported by Akther and Bhuiyan [20]. The PPTMA thin films have a slightly different structure from that of the monomer.…”

Optical characterization of plasma‐polymerized pyrrole‐N,N,3,5‐tetramethylaniline bilayer thin films

“…In their study, FTIR, UV–vis, X‐ray photoelectron spectroscopy (XPS), atomic force microcopy (AFM), and deposition rate characterization revealed that the plasma synthesis conditions affected the chemical structure, surface composition, morphology, and property of the plasma deposited films. Akther and Bhuiyan13 did the FTIR and UV–vis spectroscopic investigation of plasma‐polymerized N,N ,3,5‐tetramethylaniline (PPTMA) thin films. The structural analysis revealed that PPTMA thin films are formed with certain amount of conjugation that modifies on heat treatment.…”
