A transparent paper made of chitin nanofibers (ChNF) is introduced and its utilization as a substrate for flexible organic light-emitting diodes is demonstrated. Given its promising macroscopic properties, biofriendly characteristics, and availability of the raw material, the utilization of the ChNF transparent paper as a structural platform for flexible green electronics is envisaged.

SJR Q1NPG Asia MaterialsOA

Metal-oxide semiconductors have attracted considerable attention as next-generation circuitry for displays and energy devices because of their unique transparency and high performance. We propose a simple, novel and inexpensive ‘aqueous route’ for the fabrication of oxide thin-film transistors (TFTs) at low annealing temperatures (that is, <200 °C). These results provide substantial progress toward solution-processed metal-oxide TFTs through naturally formed, unique indium complex and post annea

Thermally Stable Transparent Sol−Gel Based Siloxane Hybrid Material with High Refractive Index for Light Emitting Diode (LED) Encapsulation
Joon-Soo Kim, SeungCheol Yang, Byeong‐Soo Bae
SJR Q1Chemistry of Materials

Nonhydrolytic sol−gel condensation for the synthesis of nanosized inorganic−organic hybrid resin and hydrosilylation reaction under a Pt catalyst for the fabrication of oligosiloxane-based hybrid material (phenyl hybrimer) were used in this research. This combination of two chemical reactions results in material with useful properties for light emitting diode (LED) encapsulation. Until now, no polymers and phenyl polysiloxane materials have been reported with a high refractive index (over 1.52)

Gwang‐Mun Choi, Jungho Jin, Dahye Shin, Yun Hyeok Kim, Jihoon Ko, Hyeon‐Gyun Im, Junho Jang, Dongchan Jang, Byeong‐Soo Bae
SJR Q1Advanced Materials

A flexible hard coating for foldable displays is realized by the highly cross-linked siloxane hybrid using structure-property relationships in organic-inorganic hybridization. Glass-like wear resistance, plastic-like flexibility, and highly elastic resilience are demonstrated together with outstanding optical transparency. It provides a framework for the application of siloxane hybrids in protective hard coatings with high scratch resistance and flexibility for foldable displays.

Optically Transparent Multiscale Composite Films for Flexible and Wearable Electronics
Young‐Woo Lim, Jungho Jin, Byeong‐Soo Bae
SJR Q1Advanced Materials

One of the key breakthroughs enabling flexible electronics with novel form factors is the deployment of flexible polymer films in place of brittle glass, which is one of the major structural materials for conventional electronic devices. Flexible electronics requires polymer films with the core properties of glass (i.e., dimensional stability and transparency) while retaining the pliability of the polymer, which, however, is fundamentally intractable due to the mutually exclusive nature of these

As demands for high pixel densities and wearable forms of displays increase, high-resolution printing technologies to achieve high performance transistors beyond current amorphous silicon levels and to allow low-temperature solution processability for plastic substrates have been explored as key processes in emerging flexible electronics. This study describes electrohydrodynamic inkjet (e-jet) technology for direct printing of oxide semiconductor thin film transistors (TFTs) with high resolution

Abstract The cuticles of insects and marine crustaceans are fascinating models for man‐made advanced functional composites. The excellent mechanical properties of these biological structures rest on the exquisite self‐assembly of natural ingredients, such as biominerals, polysaccharides, and proteins. Among them, the two commonly found building blocks in the model biocomposites are chitin nanofibers and silk‐like proteins with β‐sheet structure. Despite being wholly organic, the chitinous protei

Journal of Materials Chemistry

UV curable cycloaliphatic epoxy functionalized oligosiloxane resin is synthesized by non-hydrolytic sol–gel reaction for application in encapsulation of organic light emitting devices (OLEDs). The physical and chemical properties of polymerized cycloaliphatic epoxy hybrid materials (hybrimers) are easily tunable by controlling the precursors. A single hybrimer coating on a PET film is optically transparent and shows low permeability of up to 0.68 g m−2 day−1 per mil measured by a Ca degradation
