Effect of Irradiation and Detection of Long-Lived Polyenyl Radicals in Highly Crystalline Ultra-High Molar Mass Polyethylene (UHMMPE) Fibers

Forster, Amanda L.; Tsinas, Zois; Al-Sheikhly, Mohamad

To improve properties such as thermal conductivity, low temperature thermal strain, and creep resistance of ultra-high molar mass polyethylene (UHMMPE) fibers, several researchers have previously undertaken efforts to crosslink these fibers using radiation. Ionizing radiation is commonly used to crosslink bulk UHMMPE in other applications, such as artificial joints. However,…

3D-Printing of Pure Metal–Organic Framework Monoliths

Lim, Gwendolyn J. H.; Wu, Yue; Shah, Bhuvan B.; Koh, J. Justin; Liu, Connie K.; Zhao, Dan; Cheetham, Anthony K.; Wang, John; Ding, Jun

Metal–organic frameworks (MOFs) are usually synthesized in powder form. For many practical applications, MOFs need to be shaped into monoliths that can be easily handled. However, conventional shaping methods, such as pelletization, often result in a decrease in functionality. Recently, MOF-containing monoliths have been made using direct ink writing (DIW;…

Ion transport, polarization and electro-responsive elelctrorheological effect of self-crosslinked poly(ionic liquid)s with different counterions

Liu, Yang; Zhao, Jia; He, Fang; Zheng, Chen; Lei, Qi; Zhao, Xiaopeng; Yin, Jianbo

Self-crosslinked bis(imidazolium)-based poly(ionic liquid)s (PILs) containing different counterions (P, X = BF4−, PF6−, TfO−, TFSI−) are synthesized and the influence of counterions on electro-responsive electrorheological (ER) effect is studied in order to understand the structure-property relationship of crosslinked PIL-based ER system. It is found that the size and type of…

Construction of Dual Orientation Crystalline Structure in Poly(vinyl alcohol)/Graphene Oxide Nano-Composite Hydrogels and Reinforcing Mechanism

Meng, Yeqiao; Zhao, Xiaowen; Ye, Lin

Oriented poly(vinyl alcohol) (PVA)/graphene oxide (GO) nanocomposite hydrogels with different draw ratios were prepared by stretching during a freezing/thawing process. The PVA/GO samples with a draw ratio of 200% had significantly enhanced mechanical properties by formation of a microfibrillar structure, while the tensile strength and compressive modulus respectively reached as…

Restricting Effect of Solvent Aggregates on Distribution and Mobility of CuCl2 in Homogenous Catalysis

Wang, Yongtao; Wang, Guanqi; Yao, Jia; Li, Haoran

Extensive experimental and theoretical studies have proven the existence of solvent aggregates in alcohols, and some attempts have been made to explore the uneven distribution of solutes. Here, we studied the distribution and mobility of CuCl2 in 3-hexanol and ethanol and investigated the aerobic oxidation of 2,3,6-trimethylphenol under these systems.…
