A facile and novel fabrication method is demonstrated for creating flexible poly(ethylene terephthalate) (PET)-embedded silver meshes using crack lithography, reactive ion etching (RIE), ink. The width spacing in a waterborne acrylic emulsion polymer are controlled by the thickness of applied stress due to heating evaporation. Our innovative technique eliminates need sputtering ensures stronger adhesion metal PET substrate. Crack trench depths over 5 μm line widths under have been achieved....
Abstract Simulation and experimental studies are carried out on single‐layer double‐layer embedded metal meshes (SLEMM DLEMM) to assess their performance as transparent electromagnetic interference (EMI) shielding. The structures consist of silver in polyethylene terephthalate (PET). As a electrode, SLEMMs exhibit transparency 82.7% sheet resistance 0.61 Ωsq −1 well 91.0% 1.49 . This corresponds figures merit 3101 2620, respectively. achieve 48.0 dB EMI shielding efficiency (SE) the...
Abstract The morphology of regular and uniform arrays black silicon structures was evaluated for bactericidal efficacy against gram-positive, non-motile Staphylococcus epidermidis ( S. ). In this study, were fabricated using nanosphere lithography deep reactive ion etching. effects nanomorphology on bacterial killing systematically nanostructures with pitches ranging from 300 to 1400 nm pitch spherical cocci approximately 500 1000 in diameter. Our results show that nanostructure factors such...
Organic light-emitting diodes (OLEDs) have great potential for use in large-area display and lighting applications, but their widespread adoption large areas is hindered by the high cost insufficient performance of indium tin oxide (ITO) anodes. In this study, we introduce an alternative anode material – a silver mesh embedded glass to facilitate production OLEDs. We present facile, scalable manufacturing technique create aspect ratio micromeshes provide planar geometry needed OLED layers....
This study evaluates the performance of graded refractive index (GRIN) anti-reflective (AR) structures on photovoltaic (PV) modules across twenty global locations and compares them with conventional thin film AR coatings bare glass. Optimized glass nanocones were chosen to represent GRIN structures. Electrodynamic simulations conducted assess reflection properties at multiple angles incidence. dramatically reduce total solar-integrated 0.2% normal incidence, compared 3.8% for 0.8% optimized...
