Acetylation improves thermal stability and transmittance in FOLED substrates based on nanocellulose films

Abstract

Bleached softwood pulp was used to prepare nanofibrillated cellulose (NFC) by mechanical grinding and a high-pressure homogenization process.

Amphiphilic Modified Galactomannan as a Novel Potential Carrier for Hydrophobic Compounds

“…Therefore, the initial blocking of the hydroxyl end group blocks to some extent the second degradation process (Persenaire et al, 2001). Works with other polymers also showed that their acetylation lead to an increase of the thermal stability of the modified polymer (Hung et al, 2017;Yang et al, 2018b).…”

Hydrophobization of up-conversion luminescent films based on nanocellulose/MF2:Ho particles (M = Sr, Ca) by acrylic resin

“…Luminescent nanocomposites with a nanocellulose matrix are light-weight, flexible, thin materials with sufficient mechanical strength. These nanocomposites can be used in a number of practical applications, including: miniature biosensors and chemosensors [12][13][14][15][16][17][18][19][20], photodetectors [21,22], organic light-emitting diodes [23,24], organic solar cells [25], anti-counterfeiting [26] and different photonics devices [27][28][29].…”

Transparent and Water-Resistant Composites Prepared from Acrylic Resins ABPE-10 and Acetylated Nanofibrillated Cellulose as Flexible Organic Light-Emitting Device Substrate

“…FOLED displays will have a profound impact on the application of wearable and portable devices, and will be widely used with the continuous development of personal intelligent terminals [ 10 , 11 , 12 , 13 ]. With the growing sophistication of organic light-emitting materials and device technologies, FOLEDs are regarded as promising technology for future displays [ 6 , 14 ].…”

“…Thus, the quality of the substrate determines the performance and life expectancy of the device. The FOLED substrate should be smooth and flat, with good dimensional stability, high flexibility, good thermal stability, high transparency, and good barrier properties [ 14 ]. Additionally, substrate materials impact the following processes: electrode deposition, barrier coating, patterning exposure, and thin-film transistor fabrication.…”

“…Our previous studies found that acetylated nanofibrillated cellulose (ANFC) films, such as FOLED substrates, have many advantageous properties, including a smooth surface, high flexibility, and good thermal and mechanical properties. However, the light transmittance of NFC films was about 70%, and had not reached the 80% requirement for FOLED substrates [ 14 ]. Its water resistance also needed to be enhanced.…”
