“…Next, PSI-4 and PSI-5 possess outstanding thermal−mechanical stabilities with T s over 200 °C, which has rarely been found in elastomers. 47,48 The CTEs of PSI-linear, PSI-1, PSI-2, PSI-3, PSI-4, and PSI-5 calculated from 50 to 150 °C are 348, 351, 1208, 477, 305, and 283 ppm K −1 , respectively, indicating that the PSIs with high TAB contents are potential in thermosetting and elastomeric materials. The dimensional changes of PSIs first increase from PS-linear to PSI-2 and then decrease with more cross-linking.…”

In the development of organic electronics, polyimide (PI)-based materials have drawn significant research attention due to their remarkable features, including a simple synthesis, solution processability, outstanding thermal stability, and respectable mechanical strength. Despite the good electronic performance of PI-based materials, a high elastic modulus over 1 GPa and a modest elongation at break of the conventional PIs have restricted their applications in stretchable electronics. To address this issue, poly(siloxane imide) (PSI) with a soft siloxane chain has been proposed to achieve a significantly reduced modulus and an increased stretchability. However, previous works revealed the weak mechanical strength of PSI, in which the latest reported stretchable device comprising PSI thin film could only sustain a tensile strain below 40%. Herein, in the present study, we developed a thermally stable and mechanically durable PSI network through the polyaddition–condensation reaction between 4,4′-oxidiphthalic anhydride, aminopropyl-terminated polydimethylsiloxane, and varied amounts of 1,3,5-triaminophenoxybenzene (TAB) as a cross-linker. An optimal PSI network with 11.1% TAB exhibited a high decomposition temperature at 426 °C, a softening temperature over 200 °C, an elongation at break over 400%, a superior toughness at 13.29 MJ m–3, and low strain hysteresis. Owing to the improved solubility of PSI, the polymer elastomer can be processed as a substrate material or thin-film active layer with good mechanical properties. Finally, all-solution-processed, stretchable, and durable electronic devices including resistive memory and organic field-effect transistors were fabricated using the designed PSI with an affordable and feasible solution process. This work underlines the importance of network design on soft polymers to create mechanically tough and durable elastomers for next-generation stretchable electronics.

“…Thus, the environmental contamination caused by discharging waste cooking oil into water or soil can be avoided. Epoxidized vegetable oil (EVO) can be extensively utilized as a feedstock to synthesize polyols, glycols, and carbonyl compounds for the production of biolubricants, − biodiesel, − polyols for polyurethanes, − plasticizer, − resins, − cross-linked polymers, − pressure sensitive adhesives, , printing ink, and protective coatings. , The biobased lubricants produced from vegetable oil epoxidation are degradable with better lubricity, higher viscosity, and pour point as well as a lower viscosity index. , The biobased polyols have high average hydroxyl group functionality and thus ensure the production of rigid polyurethanes with high dimensional as well as good mechanical and thermal stability …”

Epoxidized vegetable oils obtained from either edible or nonedible vegetable oil have drawn extensive attention ascribing to the inherent nature of good biodegradability, renewableness, nontoxicity, and environmental friendliness. It has a broad application in the chemical industry, e.g., biolubricants, polyurethane, cross-linked polymers, coatings, and biodiesel. Currently, it is produced industrially by a homogeneous epoxidation process using in situ formed peracarboxylic acid. However, this method gives poor selectivity toward epoxides and causes severe corrosion to reactors. Efficient and recyclable heterogeneous metal-based materials have become promising alternatives for vegetable oil epoxidation due to the good activity and selectivity in the absence of any corrosive acids. Hence, the development of highly active, selective, and stable heterogeneous catalysts for the epoxidation of vegetable oils and their derivatives has becoming a major task for both academic and industrial communities. In this work, we have reviewed and summarized the most recent progress of catalysts development in the aspects of catalysts preparation, morphology, reusability, structure−function relationship, and reaction mechanism in the past five years. The effects of solvent, oxidant, type of reactor, and operating conditions as well as the reaction kinetics will also be reviewed and discussed to provide guidance for the future study of vegetable oil epoxidation.
