“…The shift of T α toward a higher temperature in presence of CB particles can result from the strong cohesive interactions between the matrix and the CB particles via the ester side group of the polar butyl acrylate monomer . Such a phenomenon was also evidenced in our previous work by comparison of the molecular mobility and the rheological behavior of two polystyrene PS‐fullerene C 60 systems that is, PS‐C 60 linked by strong covalent bond (grafted system) and simple physical blend PS/C 60 (weak physical interaction) . It is well established that the increase of T α is often correlated to the presence of an immobilized interphase layer of the polymer phase on the filler surface assuming a reduced mobility of the chains at this interphase .…”

Hyperelastic behavior and dynamic mechanical relaxation in carbon black‐polymer composites

et al. 2018

Tensile and thermo‐mechanical properties of nano‐composites fabricated by mechanically mixing semi‐crystalline ethylene‐co‐butyl acrylate (EBA) and carbon black (CB) nanoparticles are investigated. Stress–strain curves performed on samples over a broad range of CB content evidence the hyperelastic behavior of the EBA matrix. Neo‐Hookean and Mooney‐Rivlin models are used to fit the observed linear and nonlinear mechanical behaviors, respectively. The thermo‐mechanical curves highlight two relaxation phenomena depending on the CB content. Correspondingly, the EBA/CB interface properties are analyzed by correlating the volume fraction of the constrained polymer to the relaxation behavior of the viscoelastic linear regime. POLYM.

“…The strong research efforts on polymer semiconductors are related to the promise of their potential capability for producing low-cost, large-area, flexible electronic devices. New processes for large-size production are nowadays being actively developed targeting mainly organic photovoltaic applications [8]. In the research laboratory, semiconducting polymers are usually processed from solution by drop-casting, spin-coating or ink-jet printing.…”

Solventless processing of conjugated polymers—A review

et al. 2014

View full text Add to dashboard Cite

The molecular mobility of polymers in their solid or molten states allows their processing without the need for toxic, "non-friendly" solvents. In this work, the main features of solvent-free processing methods applied to conjugated polymers are reviewed taking into consideration that these materials are largely used in a broad range of (opto-)electronic applications, including organic field-effect transistors, polymer light-emitting diodes and polymer photovoltaic devices. This review addresses the main advantages of processing such materials in their solid state offering an alternative fabrication scheme for several opto-electronic devices. Moreover, the properties of polymer-based opto-electronic devices are largely dependent on the conformations and orientations of polymer molecules in the corresponding polymer thin film layers; especially the ordering of conjugated polymer molecules in the active layer has been a topic of intense research in organic electronics. Therefore, this review also highlights the control of conjugated polymer molecule ordering when using solvent free processing techniques. Finally, conclusions and perspectives of solventless processed conjugated polymer molecules in organic electronics are addressed.

“…Polymer-fullerene solar cells were among the first materials applied in the aforementioned type III organic solar cells. 10,11 Poly(thiophene) is one of the most applied polymers for organic solar cells, 13 since it presents desirable optical properties, thermal, and environmental stability with potential applications on electronics, photovoltaics, sensors, and transistors. It should be mentioned that polymeric heterojunctions can exhibit different architectures, such as: (a) bilayer (with limitations, due to the active layer length), (b) bulk heterojunction, and (c) ordered heterojunction.…”

“…8 Organic solar cells are considered as low cost alternative materials with mechanical flexibility [9][10][11][12] and potential variation of their bandgap through the incorporation of different polymers, in order to harvest more efficiently the solar spectrum. 10,11 Poly(thiophene) is one of the most applied polymers for organic solar cells, 13 since it presents desirable optical properties, thermal, and environmental stability with potential applications on electronics, photovoltaics, sensors, and transistors. 14,15 Unfortunately, the low solubility of poly(thiophene) in most organic solvents has led to the use of either substituted poly(thiophenes) or block copolymers with poly(thiophene) as one of the blocks.…”

In this manuscript mixtures of a poly(styrene)-b-poly(thiophene) (PS-b-PT) copolymer with fullerenes (C 60 ) as a dopant were prepared in order to evaluate their optical/surface properties through optical microscopy (OM) and atomic force microscopy (AFM) measurements respectively, as well as their conductivity through the four probe technique under variable conditions such as: temperature (room temperature and 150 C), solvent (toluene and chlorobenzene) and dopant concentration (2 and 5 wt %). The results exhibited that thermal treatment; solvent polarity and dopant concentration influence significantly the optical absorbance values. Ultraviolet-visible spectroscopy (UV-Vis) was also adopted to examine the optical absorbance of the mixtures and how it can be affected by the structures obtained in each case. The results for the variables involved in this study were very interesting and led to significant conclusions concerning the potential application of the proposed mixture for improved organic solar cells.
