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.

The dataset consists of the results of cure kinetics, glass transition advancement, chemorheology and stress relaxation experiments for the DGEBA/4-APDS epoxy vitrimer. The heading of each column contains the quantity measured and the unit of measurement. The cure kinetics dataset (Cure-kinetics-dataset.xlsx) comprises time-temperature profiles and degrees of cure attained as well as the associated reaction rate data for 4 dynamic DSC experiments (1.25°C/min, 2.5°C/min, 5°C/min and 10°C/min) and 7 isothermal DSC experiments (140°C, 150°C, 160°C, 170°C, 180°C, 190°C and 200°C). Experimental results for each temperature and rate are presented in a separate spreadsheet. The chemorheology dataset (Chemorheology-dataset.xlsx) contains time, temperature and viscosity profile for 5 isothermal experiments (80°C, 90°C, 100°C, 110°C and 120°C). Experimental results for each temperature are presented in a separate spreadsheet. The stress relaxation dataset (Stress-relaxation-dataset.xlsx) contains decay time, temperature, stress, strain and relaxation modulus obtained in 5 isothermal experiments (180°C, 190°C, 200°C, 210°C and 220°C). Each spreadsheet represents an experiment at a particular temperature. The Tg advancement dataset (Tg-advancement-dataset.xlsx) contains time, temperature and heat flow profiles for 18 experiments carried out on partially cured samples. The data are organised in spreadsheets per DSC test; the thermal profile prior to the experiments is as follows: - Tg_1.25°C-min-220°C: DSC of uncured resin. - Tg_1.25°C-min-130°C: DSC of resin partially cured at 1.25°C/min from -50°C to 130°C. - Tg_1.25°C-min-136°C: DSC of resin partially cured at 1.25°C/min from -50°C to 136°C. - Tg_1.25°C-min-140°C: DSC of resin partially cured at 1.25°C/min from -50°C to 140°C. - Tg_1.25°C-min-145°C: DSC of resin partially cured at 1.25°C/min from -50°C to 145°C. - Tg_1.25°C-min-150°C: DSC of resin partially cured at 1.25°C/min from -50°C to 150°C. - Tg_1.25°C-min-160°C: DSC of resin partially cured at 1.25°C/min from -50°C to 160°C. - Tg_1.25°C-min-170°C: DSC of resin partially cured at 1.25°C/min from -50°C to 170°C. - Tg_1.25°C-min-180°C: DSC of resin partially cured at 1.25°C/min from -50°C to 180°C. - Tg_1.25°C-min-190°C: DSC of resin partially cured at 1.25°C/min from -50°C to 190°C. - Tg_2.5°C-min-170°C: DSC of resin partially cured at 2.5°C/min from -50°C to 170°C. - Tg_5°C-min-170°C: DSC of resin partially cured at 5°C/min from -50°C to 170°C. - Tg_10°C-min-170°C: DSC of resin partially cured at 10°C/min from -50°C to 170°C. - Tg_iso10min_150°C: DSC of resin partially cured isothermally at 150°C for 10 minutes. - Tg_iso20min_150°C: DSC of resin partially cured isothermally at 150°C for 20 minutes. - Tg_iso30min_150°C: DSC of resin partially cured isothermally at 150°C for 30 minutes. - Tg_iso40min_150°C: DSC of resin partially cured isothermally at 150°C for 40 minutes. - Tg_iso100min_150°C: DSC of resin partially cured isothermally at 150°C for 100 minutes (fully cured).
