“…Specifically, the microplasma printer, which is a multi‐needle‐to‐plate dielectric barrier discharge (DBD) system, enables a dot‐wise plasma ignition on the surface. The microplasma printer was originally adopted for surface treatment and functionalization using nondepositing gases such as N 2 /O 2 mixtures . An example of patterning application was already mentioned above: a novel two‐step process for submillimeter scale area‐selective ALD of transparent conductive oxides by activation of H‐terminated Si using a microplasma printer before In 2 O 3 :H deposition by ALD .…”

A microplasma printer is employed to deposit thin film patterns of TiO2 by titanium tetra‐isopropoxide and N2/O2 plasma at atmospheric pressure. The setup is adopted to carry out deposition in two configurations, namely under chemical vapor deposition (CVD) and atomic layer deposition (ALD) modes. The properties of TiO2, as well as the patterning resolution, are investigated. The amorphous TiO2 deposited in the CVD mode contains a relatively high level of impurities (residual carbon content of 5–10 at.%) and is characterized by a low refractive index of 1.8. With the ALD mode on the other hand, TiO2 is obtained with a low level of impurities (<1 at.% C and <2 at.% N), a refractive index of 1.98, and a growth per cycle of 0.15 nm. Furthermore, the spatial resolution for a 8‐nm‐thick film is determined by X‐ray photoelectron spectroscopy line scan and found to be equal to 2,000 and 900 µm for the CVD and ALD modes, respectively. This study can be regarded as the first step toward area‐selective CVD and ALD of TiO2 by a microplasma printer, which can be further explored and extended to other material systems.

“…As such, the purpose of using UV-ozone treatment is to improve the wettability of the silver ink overprinted onto the dielectric layer. Much literature abounds in the use of UV-ozone treatment to obtain more hydrophilic surfaces [29][30][31], with the extent of hydrophilicity dependent on the UV-ozone exposure time [25][26][27][28].…”

Surface and Coatings Technology, 266, Additional Information:• This article was accepted for publication in the journal, Surface and Coat- AbstractThere has been much interest in the printing of silver inks onto flexible substrates, for which intermediate dielectric layers are often required to achieve suitable wettability. This work seeks to realize continuous silver traces overprinted onto UV-curable dielectrics through surface modification techniques (thermal and UV-ozone post treatments), when the UV light source used for the curing is non-optimal. Two UV curable dielectric materials were deposited and the effects of curing time and curing atmosphere on the inkjet printability of a commercially available silver ink were investigated. Good wettability of the silver ink was obtained following ozone treatment of the dielectric layers, where the treatment required was found to be a function of the dielectric formulation and the curing atmosphere. Water droplet contact angle measurements were used to analyse the resulting changes in the surface conditions of the dielectric layers. The results provided an indication, but were not sufficient for predicting whether silver traces with measurable resistance could be subsequently obtained. Instead, measurable silver trace resistances were found to be influenced by the occurrence of cracks in the trace and possibly the degree of cross-linking present in the dielectric. Following these results, the authors demonstrate that electrically conductive traces can be achieved on ambient cured samples, which yields a more flexible solution compared to inert cured samples.

Bacteriorhodopsin (BR) is a transmembrane protein which able to transport protons through cell membrane and thus converting solar energy to electrical energy. Up to now different strategies have been used to immobilize BR. In the present study the BR has been immobilized on polycarbonate surface with two different methods. The functional groups of polycarbonate were modified in two ways (sulfuric acid, PDAC and HNO3) and then the BR was immobilized on two different modified polycarbonate surfaces. The modified surfaces were characterized by ATR-FTIR and AFM techniques. Afterward the activity of bounded BR to two different modified polycarbonate surfaces was measured. Our results show that BR bounded to modified polycarbonate surface with HNO3 (nitrated polycarbonate) has higher activity in comparison to modified with sulfuric acid (electrostatically bounded BR). Also the activities of both types of Bounded BR after 10 days were measured. The results showed that unlike electrostatically bounded BR, bounding BR to nitrated polycarbonate keeps its activity after 10 days. In conclusion, nitrated polycarbonate surface is a suitable candidate due to immobilizing BR in order to manufacture of BioCDs.
