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.…

TBAH(tetra-butylammonium hydroxide)/Urea/H2O solvent has been applied for the solvent wet-spinning of cellulose, due to its room temperature operation, good stability and spinnability of the cellulose solution, as well as the unconditional string of low DP (degree of polymerization) for dissolving cellulose. Most importantly, it is found that the stability of…

Structure Evolution of Polyethylene in Sequential Biaxial Stretching along the First Tensile Direction

Chen, Qiang; Chen, Dandan; Kang, Jian; Cao, Ya; Chen, Jinyao

Two linear low-density polyethylene samples (PE-A and PE-B), with similar melt index and molecular weight but different molecular structures, were used to explore the structural evolution during sequential biaxial stretching. Only PE-A could be successfully stretched into a film with the biaxial draw ratio of 6 × 6. The interlamellae…

Sustainable network polymer via dynamic metal ionic crosslinks

Wang, Yanjun; Lei, Yuan; Zhou, Changlin; Wu, Bo; Jiang, Yuanyuan; Lei, Jingxin

Incorporating reversible dynamic linkages into the polymer networks endows traditional thermosets with recyclability and reprocessability. However, the facile preparation of recyclable polymer networks with suitable stability and acceptable cost is still a challenge. Among various dynamic linkages, ionic bonds promise a rational dynamic linkage in virtue of suitable stability and…

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…
