Tracking the interdiffusion of polymers at a molecular level by 1H dipolar filter solid-state NMR under fast magic angle spinning
In this paper, we characterized the interdiffusion of deuterated polystyrene (PS-D) and hydrogenated poly(2,6-dimethyl-1,4-phenylene oxide) (PPO) by 1H dipolar filter solid-state NMR under fast magic angle spinning (MAS). It is observed that the interdiffusion process of PS-D/PPO is composed of two stages, the wetting stage and the diffusion stage. The characteristic time of the transition from th...

Prediction of dielectric dissipation factors of polymers from cyclic dimer structure using multiple linear regression and support vector machine
A quantitative structure–property relationship (QSPR) study was performed for the prediction of the dielectric dissipation factors tanδ of polymers by using multiple
linear regression (MLR) and support vector machine (SVM) methods. Molecular descriptors of the polymers were calculated from their corresponding cyclic dimer structures. The obtained models with the frequency of measureme...

Solvothermal synthesis and structures of three novel heterometallic microporous coordination polymers assembled from 2-hydroxy-nicotinic acid
Three novel heterometallic microporous coordination
polymers {M(Hnico)3M0}n (1, M = Co, M0 = K; 2, M = Ni, M0 = K; 3, M = Co, M0 = Na, Hnico is the anion of 2-hydroxy-nicotinic acid, where the proton is transferred from the phenolate hydroxy group to the
nitrogen atom of imine pyridine ring) were synthesized by
hydrothermal reaction between M(Ac)24H2O, M0OH and a multifunctional organic aromat...

Synthesis and Crystal Structures of Two Heterobinuclear Nickel Polymers [NiNaL(dca)]n and [NiNaL(dca)]2n·(CH3COOCH3)n·(H2O)n
At the same condition, utilizing the different of base, the authors
constructed two wholly different compounds, 1 and 2. Compounds
1 and 2 are one-dimensional (1D) chainlike, while the coordination
mode of dicyandiamide is different in both complexes. In 1, the
dicyandiamide is μ1,5-dca bridged coordination mode; in 2, that is
μ1,3-dca bridged coordination mode. Two new heterobinuclear nick...

β-cyclodextrin and its hyperbranched polymers-induced micro/nanopatterns and tunable wettability on polymer surfaces
This paper reports an efficient strategy to fabricate micro/nanopatterns on the surfaces of polymers for obtaining tunable wettability. Tepee-like bundles as micro/nanopatterns, composed of irregular polygon ‘‘podium’’ and ‘‘valley’’ structures, are formed by adding b-cyclodextrin (b-CD) or its hyperbranched polymers [HBP(b-CD)s] into a polystyrene (...
