The main goal of this paper was to study the optical, electrical, and thermal properties of hybrid composites based on biodegradable polymers (L,D-poly(lactic acid), polycaprolactone or Ecoflex®), single walled carbon nanotubes (SWCN), and 4′-pentyl-4-biphenylcarbonitrile (5CB). The biodegradable polymers’ binary and ternary compositions were analyzed in detail by ultraviolet and visible (UV–Vis) spectroscopy taking into consideration their chemical structure and interactions with 5CB and SWCN. Differential scanning calorimetry (DSC) studies of the created hybrid layers showed thermal stability and changes in glass transition temperature and melting point in comparison to neat polymers, depending on the chemical structure of the polymer used and the type of composition. Morphology of the created layers were investigated by atomic force and polarizing microscopy. The static contact angle measurements of a water drop showed that all of the neat polymer layers were hydrophobic with angle values ranging from 108° to 115°. In addition, in the case of the Ecoflex® layers, both with and without additives, a rapid sorption of the deposited water drop was observed. Finally, a simple device with poly(ethylene terephthalate) (PET)/indium tin oxide (ITO)/poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS)/poly [[4,8-bis[(2-ethylhexyl)oxy]benzo[1,2-b:4,5-b′]dithiophene-2,6-diyl][3-fluoro-2-[(2-ethylhexyl)carbonyl]thieno[3,4-b]thiophenediyl]] (PTB7): [6,6]-phenyl-C71-butyric acid methyl ester (PC70BM)/Ag/biodegradable polymer:SWCN architecture was constructed and tested using an infrared (IR) thermographic camera to investigate the surface defects on the created hybrid layers. Increasing the SWCN admixture from 0.01 to 0.5% significantly improved the conductivity only in the case of L,D-poly(lactic acid):SWCN (10:0.5), for which above 5 V, a current with a resistance of 3030.7 Ω could be measured. In order to use the created layers as flexible electrodes, the first experiments were carried out with an admixture of SWCN and poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) as conductive compounds.

Overview of printing and coating techniques in the production of organic photovoltaic cells

The organic photovoltaic cell (OPV) is composed of multiple layers, and some printing and coating techniques are more suitable than others for a certain type of layer. This paper aims to characterize and compare the most relevant coating and printing techniques that can be used in the manufacture of OPVs. Extensive bibliographic research was carried out on articles published from 1998 to 2020 to identify various aspects OPV, such as the principle of operation, advantages, disadvantages, and which layers can be printed by each technique. The results show that the most used method for the processing of OPVs is spin-coating. In the studies found, rotation was used to coat the active layer, the electron transport layer, and the hole transport layer. The techniques of pad printing, casting, and meniscus are considered useful in the processing of the active layer. Regarding the deposition of the active layer, hole transport layer, electron transport layer, and anode, the rotogravure, crack matrix, spraying, and brushing techniques were satisfactory. Flexography has been used to form the active layer, electron transport layer, and anode. Screen printing, inkjet printing, and knife/blade coating were used in the processing of the active layer, hole transport layer, electron transport layer, anode, and cathode. All the double slot die coating, curtain coating, and slide coating allows simultaneous processing of multiple layers. Techniques compatible with roll-to-roll processing are more likely to be at the center of OPVs in the future, thus making solar photovoltaic technology more competitive.

Wearable and implantable devices play a crucial role in clinical diagnosis, disease treatment, and fundamental research on the body's electrophysiology and biochemical processes. Conducting polymers are emerging as promising solutions to surpass the limitations of traditional metal‐based electrodes, offering enhanced conformability, and stretchability. However, current microfabrication techniques of CP electrodes have a number of limitations. In this study, a novel wet‐printing technique is developed for the fabrication of highly stretchable poly(3,4‐ethylenedioxythiophene): polystyrene sulfonate (PEDOT:PSS) microelectrodes. The wet‐printing, conducted in a liquid coagulation bath, has the advantages of being non‐contact, easy and fast to perform, and capable of printing low‐viscosity inks. Wet‐printing of PEDOT:PSS lines with a width of ≈20 µm is demonstrated. By adding D‐sorbitol as a plasticizer, an ultra‐high stretchability of PEDOT:PSS electrodes, of more than 720% is achieved while the electrodes remained conductive and strain‐insensitive up to high strains. The use of PEDOT:PSS wet‐printed electrode arrays for the electrophysiological recording from the stomach is demonstrated. The stretchable electrodes conformed swell to the tissue and recorded comparable electrophysiological signals to Au‐plated electrodes in porcine and rodent animal models. The wet‐printing approach to fabricating flexible and stretchable electrode arrays using low‐viscosity, conducting inks holds promise for applications in conformable electronics.
