“…Одним из недавно предложенных методов улучшения стабильности перовскитов является добавление в перовскиты этилцеллюлозы, формирующей водородные связи с CH 3 NH 3 MX 3 , что стабилизирует кристаллическую структуру металлоорганического перовскита [20][21][22]. Ранее нами были получены и исследованы электрические и оптические свойства нанокристаллов неорганических перовскитов внедренных в матрицу полупроводникового полимера [23], а также эффект введения полупроводниковых полимеров в матрицу бактериальной целлюлозы [24]. Однако влияние производных целлюлозы, таких как смешанные эфиры целлюлозы (cellulose esters, CE) [25], на электрические свойства металлоорганических перовскитов и их стабильность остается малоизученным.…”

It is shown that the introduction of a mixed cellulose esters with acetrimethyl acetate into films of organometallic perovskite CH3NH3PbBr3 significantly increases their stability while maintaining the optical and photoelectric properties of perovskite. It was found that with the introduction of 10-20 wt% mixed cellulose ester in CH3NH3PbBr3, the resistivity of the composite increases by 5-10 times within 60-70 days, while in pure perovskite films such changes are observed within 10-15 days. When the films are irradiated with a simulated sunlight, the resistance of the samples drops by 2-3 orders of magnitude, and the effect of photosensitivity persist for more than 2 months. The formation of hydrogen bonds between mixed cellulose ester and organometallic perovskite is, in our opinion, the main factor that increases the stability of the composite film in comparison with pure perovskite. The investigated composite films are promising for the design of degradation-resistant perovskite solar cells and light-emitting diodes.

Wearable electronics require thin and flexible substrate materials for user comfort. We propose a substrate material based on a nanocellulose-polyurethane matrix. The stretchability, i.e. Young's modulus and breaking strain, of the material can be tuned by nanocellulose concentration. We describe the fabrication process and demonstrate the modulation of the mechanical properties. Further, we present oxygen and water vapour permeability, as well as dielectric properties' measurements. Effects of substrate properties on printing of metallic conductors are considered. Laser cutting of the substrate and lamination of several layers of substrate material together are demonstrated, as well as hybrid integration of discrete components on the substrate. As an integrated demonstrator, a patch for local skin surface temperature measurement is presented. The patch thickness is 50μm, and it consists of two layers of the substrate material, printed metallic conductors and hybrid integrated temperature sensors.

This study discusses on an attempt to create a transparent conductive paper made by a facile process and environmentally friendly cellulose‐based sorghum as a substitute for glass coating in the display industry that has the advantage of being able to be formed and folded. Sorghum stems with a relatively high cellulose content of around 40% make it a potential material to be used as a conductive transparent paper. The isolation of microfibrillated cellulose from sorghum stem waste using chemicals and sonication methods to obtain cellulose nanofibril (CNF) within a nanometer size range are discussed in this research. Furthermore, lactic acid (LA) as a modifier is added with varying concentrations to explore the effect of its addition on the processing of the transparent paper made from the CNF. Characterization in this study includes several aspects: to investigate the morphology of the CNF paper is carried out by scanning electron microscope. In addition, thermal strength for the product is analyzed using thermal gravimetric analysis. It is found that the CNF paper with 0.5 wt% of LA able to increase paper drying time while still able to maintain the morphology of the transparent paper.
