“…4. The pristine P3OT was stable to 300°C, and its decomposition temperature was approximately 500°C, with a corresponding weight loss of approximately 70%; this result is consistent with that previously reported [17]. The TGA curves of the P3OT/carbon fiber composites indicate that the degradation temperature is approximately 20°C higher than that of pristine P3OT and that the weight loss increases with increasing P3OT content.…”

“…Due to these unique technological characteristics, the preparation of nanomembranes has become a topic of growing interest. [1][2][3][4][5][6][7][8][9] In addition to their obvious interest as cell substrates for tissue engineering applications, robust membranes of macroscopic size and nanometric thickness could provide a unique family of drugdelivery vehicles, biomimetic systems, microfluidic valves, platforms for biosensors, wound dressing and even artificial organs. Within this context organic-inorganic hybrid nanomembranes (l z 35 nm) with an interpenetrating network structure deserve a special mention since the hybridization of cross-linked polymers (e.g.…”

“…Ultrathin films based on conducting polymers (CPs), like polythiophene derivatives, or on mixtures of conventional insulating polymers and CPs have been reported to present semiconductor behavior, high environmental stability and good mechanical properties, opening a new route for the fabrication of organic nanotransistors for electronic devices. [6][7][8][9] Moreover, the application of CPs at the interface between biology and electronics has been found to be useful for the development of implants for tissue engineering 10,11 and nerve regeneration, 12 mechanical actuators (artificial muscles), 13 sensors, 14,15 etc. In recent studies we evidenced that CPs typically behave as a cellular matrix.…”

The present study reports the fabrication of free-standing nanomembranes with semiconducting and biodegradable properties. Nanomembranes have been prepared by spin-coating mixtures of a semiconducting polythiophene derivative, poly(3-thiophene methyl acetate), and a biodegradable polyester, poly(tetramethylene succinate). Both the roughness and thickness of the nanomembranes, which ranged from 3 to 20 nm and from 20 to 80 nm, respectively, were precisely controlled through the spin-coater speed and the solvent evaporation properties. Nanomembranes made of conducting polymer/polyester blends, which are able to retain the properties of the individual polymers, are stable in air and in ethanol solution for more than one year, facilitating their manipulation. Enzymatic degradation essays indicated that the ultra-thin films are biodegradable due to the presence of the aliphatic polyester. Interestingly, adhesion and proliferation assays with epithelial cells revealed that the behavior of the blend as cellular matrix is superior to that of the two individual polymers, validating the use of the nanomembranes as bioactive substrates for tissue regeneration.

Different weight ratios of poly(3-octyl thiophene) / polyvinyl chloride blends were prepared using the casting method by dissolving poly(3-octyl thiophene) and polyvinyl chloride polymers in chloroform and Tetrahydrofuran, respectively. Fourier transform infrared spectroscopy indicates the existence of carbonyl group in both polyvinyl chloride neat and poly(3-octyl thiophene)-polyvinyl chloride blends. Electrical measurements reveal that the impedance values are increased with the increasing of both weight fraction of poly(3-octyl thiophene) and temperature. Optical results reveal that the increase of poly(3-octyl thiophene) weight fraction in blends enhances the UV-visible absorption of polyvinyl chloride and reduces the optical energy gap of blends. Differential scanning calorimetric measurements and thermal gravimetric analysis show that the glass transition temperature value and thermal stability of blend increases with increasing of poly(3-octyl thiophene) weight ratio. The obtained results, generally, indicate that the increase of poly(3-octyl thiophene) weight fraction enhances the interaction between poly(3-octyl thiophene)-polyvinyl chloride chains and as a result will restrict the chain mobility of polymers.
