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…

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;…

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,…

Hierarchical Sticker and Sticky Chain Dynamics in Self-Healing Butyl Rubber Ionomers

Mordvinkin, Anton; Suckow, Marcus; Böhme, Frank; Colby, Ralph H.; Creton, Costantino; Saalwächter, Kay

We present a detailed comparison of the microscopic dynamics and the macroscopic mechanical behavior of novel butyl rubber ionomers with tunable dynamics of sparse sticky imidazole-based sidegroups that form clusters of about 20 units separated by essentially unperturbed chains. This material platform shows promise for application as self-healing elastomers. Size…

Core-crystalline nanoribbons of controlled length via diffusion-limited colloid aggregation

Schmarsow, Ruth N.; Ceolín, Marcelo; Zucchi, Ileana A.; Schroeder, Walter F.

It has been previously reported that poly(ethylene) (PE)-based block copolymers self-assemble in certain thermosetting matrices to form a dispersion of one-dimensional (1D) nanoribbons. Such materials exhibit exceptional properties that originate from the high aspect ratio of the elongated nano-objects. However, the ability to prepare 1D assemblies with well-controlled dimensions is…

Isothermal and non-isothermal cold crystallization of tetrabenzofluorene (TBF) molecules

Boopathi, A. A.; Sampath, Srinivasan; Narasimhaswamy, T.

Design and synthesis of tetrabenzofluorene (TBF) derivatives are carried out to investigate the isothermal and non-isothermal cold crystallization (CC) behavior by various spectroscopic and analytical techniques. The unprecedented CC exhibited by TBF molecules is examined by systematic modification of alkyl chain length (C8–C18 even carbons) on both sides of the…

Organic acids interacting with block copolymers have broadened the window that retains isoporous structures

Zhu, Guo-Dong; Yin, Yu-Rong; Li, Zhen-Nan; Qiu, Ya-Yu; Yi, Zhuan; Gao, Cong-Jie

Evaporation is significantly important for the preparation of isoporous membranes from self-assembly and non-solvent induced phase separation (SNIPS). Unfortunately, the time of solvent evaporation that retains isoporous structures is usually rather short, which causes many challenges to fabricate membranes with repeatable and controllable isoporous structures. In the current work, we…
