“…PECVD has been used in conjunction with thiophene (and its derivatives),124–135 pyrrole,121, 133, 136 and aniline137–139 monomers. Both the chemical structure and properties of the PECVD films differ from the conducting polymers obtained by traditional wet‐synthetic methods and are dependent on the plasma‐polymerization conditions.…”

Chemical vapor deposition (CVD) polymerization utilizes the delivery of vapor-phase monomers to form chemically well-defined polymeric films directly on the surface of a substrate. CVD polymers are desirable as conformal surface modification layers exhibiting strong retention of organic functional groups, and, in some cases, are responsive to external stimuli. Traditional wet-chemical chain- and step-growth mechanisms guide the development of new heterogeneous CVD polymerization techniques. Commonality with inorganic CVD methods facilitates the fabrication of hybrid devices. CVD polymers bridge microfabrication technology with chemical, biological, and nanoparticle systems and assembly. Robust interfaces can be achieved through covalent grafting enabling high-resolution (60 nm) patterning, even on flexible substrates. Utilizing only low-energy input to drive selective chemistry, modest vacuum, and room-temperature substrates, CVD polymerization is compatible with thermally sensitive substrates, such as paper, textiles, and plastics. CVD methods are particularly valuable for insoluble and infusible films, including fluoropolymers, electrically conductive polymers, and controllably crosslinked networks and for the potential to reduce environmental, health, and safety impacts associated with solvents. Quantitative models aid the development of large-area and roll-to-roll CVD polymer reactors. Relevant background, fundamental principles, and selected applications are reviewed.

“…The appearance of the vibronic features is the signature of the close packing of P3HT polymer chain in the condensed phase [28], indicating that there is small ordering in the chains of all the P3HT films. Furthermore, a shift of the 513 nm absorbance peaks towards higher wavelengths was given for the samples synthesized for 1 h with and without MW, suggesting a decrease in energy gap related to increased conjugation chain [29]. It seems that MW radiation had no effect on the optical absorbance of the P3HT products.…”

Poly(3-hexylthiophene) (P3HT) is a semiconductor polymer that has been proved to be a good electron donor in organic or hybrid solar cells. In this work, a detailed study of P3HT synthesis in CH2Cl2solvent by oxidative method with and without MW assistance has been conducted. Effects of synthesis process parameters on the physical properties of P3HT products and their application in hybrid CdS/P3HT photovoltaic devices were studied. It is observed that the use of MW as well as the reaction time affected the reaction yield and properties of the polymer products. It was found that, by the traditional method (without MW), the maximum yield and the properties of the polymer products were similar after 2 h or 24 h of synthesis. The optimal reaction time with MW for P3HT polymerization in CH2Cl2solvent was 1 h, and the obtained P3HT product showed similar or better properties than those P3HT polymers synthesized by the traditional method in the same solvent. The effect of using MW during the synthesis was to increase yield and crystal size of P3HT. Larger energy conversion efficiency of ITO/CdS/P3HT/CP-Au devices was obtained when the P3HT product had higher molecular weight and head/tail-head/tail (HT-HT) triad contents.

Plasma‐enhanced modification of multiwalled carbon nanotube with conducting polymers for dye sensitized solar cells

This study presents the modification of multi‐walled carbon nanotube (MWCNT) with poly(3‐hexylthiophene) (P3HT) and polypyrrole (PPy) through the fast, versatile, and environmentally friendly process of radiofrequency (RF)‐rotating plasma polymerization. Morphological characterization of composites was performed using scanning electron microscopy (SEM) and showed that the P3HT and PPy conducting polymers coated the MWCNT surface. The surface properties of the MWCNT composites were determined using Fourier transform infrared spectroscopy (FTIR), X‐ray photoelectron spectroscopy (XPS), and SEM analysis. MWCNT composites were used as cathodes in dye‐sensitized solar cells (DSSCs). The short circuit current densities of P3HT/MWCNT‐ and PPy/MWCNT‐based DSSCs were found to be 5.61 and 4.19 mA/cm2, respectively. POLYM.
