“…A wide variety of printing and coating techniques have been applied to R2R printed electronics, some of which are by themselves particularly suited for R2R processing due to their intrinsic mode of operation, whereas others need to be specifically adjusted to be R2R compatible . Many reviews and textbooks describing the technologies in detail are available in the open literature, which is why we constrain ourselves here to a brief introduction.…”

The production of electronic devices using solution based ("wet") deposition technologies has some decisive technical and commercial advantages compared to competing approaches like vacuum based ("dry") manufacturing. Particularly, the potential to scale up production processes to large areas and high volumes by introducing continuous roll-to-roll (R2R) methods on flexible substrates has been the topic of intense studies from both applied research institutes and industry already for some years. Decisive steps forward have been achieved during that time, resulting in the dawn of commercial applications for a number of processes, while additional development work is still needed in some other fields. This review summarizes the work published during the last few years on the R2R printing and wet coating of electronic devices. An overview is presented of the basic operational principles for the most commonly used R2R printing and coating methods and techniques for proper web handling in R2R lines. Then, the most commonly used types of flexible substrate materials are introduced, followed by a review of the work published in the application areas of transparent conductor materials, printed electric connections, light emitting devices, photovoltaic energy generation, printed logic, and sensing.

“…The samples were exposed under a UVB lamp in a darkroom for 5 h, The process conditions of slot-die coating can be used to control the thickness of the coated layer and thereby increase the yield rate of previtamin D 3 . The dominant parameters affecting the thickness are known to be the liquid viscosity, liquid surface tension, liquid solid content, coating velocity, flow rate, and coating gap [16]. In this experiment, the capillary number is higher than 0.02 owing to the use of PMMA with an 18% concentration in the coating solution; therefore, the coating window is inappropriate for the use of the viscocapillary model [17].…”

We propose a roll-to-roll process for vitamin D3 patch production. A solution of 7-dehydrocholesterol is applied to a plastic film by roll-to-roll slot-die coating and dried by a far-infrared lamp. Upon exposure to ultraviolet B irradiation, these films are converted to previtamin D3 films. After heat-treating the previtamin D3 film, high-performance liquid chromatography measurements are performed using commercial vitamin D3 as a standard sample. The results confirm that vitamin D3 can be produced by large-area coating and post-treatment processes. Specifically, 3.16 ± 0.746 mg of vitamin D3 is obtained through ultraviolet B irradiation and heat-treatment of 24.8 ± 1.44 mg of coated 7-dehydrocholesterol.

“…20 Many materials-based publications have demonstrated that ink-jet printed silver traces providing conductive lines on various substrates can be fabricated with acceptable consistency, conductivity, and mass-produced via roll-toroll manufacturing. [23][24][25] These traces can be customized by varying the number of printed layers 26 and sintering treatments to increase conductivity. Sintering and curing techniques commonly used for printed conductive traces are electrical sintering, 27 heat annealing/baking, 28 lasers, 29 and intense pulsed light.…”
