Polymer

DGEBA/Jeffamine D230 epoxy configurations at conversion levels ranging from 0 to 80% for molecular dynamics (MD) simulations. Three different configurations are provided at each conversion level obtained using a multistep MD algorithm with different initial conditions (see details in the article). Configurations are in LAMMPS data format.

This is original data of the paper"Novel Reinforcement Behavior in Nanofilled Natural Rubber(NR)/Butadiene -acrylonitrile Rubber(NBR) Blends:Filling-Polymer Network and Supernanosphere".All the figures in the paper are got by diverse method based on the data, and I confirm that the data is original.

Interfacial behavior of the giant surfactants with precisely tethered molecular nanoparticles (MNPs) is an important topic. In this article, by the combination of hydrosilylation, esterification, and CuAAC ‘‘click’’ chemistry, poly(ethylene oxide) (PEO) chains were end-capped with particle-like aryl-trifluorovinyl ether functionalized polyhedral oligomeric silsesquioxane (FVPOSS) to construct “one-head one-tail” and “bola-form” giant surfactants. The giant surfactants are spread at air/water interface, and surface pressure-area (π-A) isotherms reveal their interfacial behaviors under compression. Atomic force microscope (AFM) images indicate that the giant surfactants show fractal growth behavior after transferred to the silicon substrate at different surface pressure through the procedure of Langmuir-Blodgett (LB) film deposition.

Supporting Information files for In-situ Synthesis of Cross-linked Imidazolium Functionalized Poly(styrene-b-isobutylene-b-styrene) for Anion Exchange Membranes The cross-linked imidazolium functionalized anion-exchange membranes is in-situ prepared via reaction of chloromethylated poly(styrene-b-isobutylene-b-styrene) with 1,1’-(1,6-hexanediyl)bisimidazole and N-methylimidazole. The composite membranes of cross-linked imidazolium poly(styrene-b-isobutylene-b-styrene) with a small amount of modified graphene oxide grafted with octadecyl and propyl phenyl imidazolium could be further prepared. These membranes exhibit significantly high chemical stability and ionic conductivity (σ), marked by low methanol permeability, together with improved dynamic mechanical properties. The ionic conductivity of cross-linked imidazolium poly(styrene-b-isobutylene-b-styrene) reaches 2.09 × 10−2 S cm−1 at 80 °C by introduction of 0.5 wt% loading of modified graphene oxide. This membrane also behaves an excellent chemical stability and σ can remain ca. 82% of the original value after immerged in strong alkaline medium (2 M NaOH) at 60 °C for 500 h, which is almost the same as that (ca. 82%) of commercial Nafion 115 in acid medium (2 M H2SO4) at 60 °C for 500 h. The cross-linked imidazolium poly(styrene-b-isobutylene-b-styrene) is characterized as a promising anion exchange membrane materials in fuel cell for its high ionic conductivity, chemical stability and low methanol permeability.
