Quantitative probing the interfacial structure of TPO/CPO blends by transmission electron microscopy via EDX

Unique Interphase and Cross-Linked Network Controlled by Different Miscible Blocks in Nanostructured Epoxy/Block Copolymer Blends Characterized by Solid-State NMR

“…A variety of experimental techniques including small-angle X-ray scattering (SAXS), transmission electron microscopy (TEM), , and nuclear magnetic resonance (NMR) were utilized to investigate the thickness and composition of the interphase of multiphase polymers. Solid-state NMR (SSNMR) spectroscopy has been proven to be a nondestructive and powerful multiscale technique to study the interphase property of polymers, including related interfacial intermolecular interactions on the length scale from the atomic level to several tens of nanometers. , Usually, high-resolution 1 H or 13 C NMR experiments provide useful information on the intermolecular interaction because of their sensitivity to local chemical environments. , Furthermore, by measuring the time scale of proton spin diffusion, the length scales in nanoscopic heterogeneities from a few angstroms up to 100 nm and the interphase between different microdomains in polymers can be well-determined. , On the basis of the differences in molecular mobility of different phases, 1 H dipolar filter spin-diffusion NMR experiments have been extensively applied to investigate the microphase structure in multiphase solid polymers, such as polymer blends, block copolymers, core–shell polymers, and so on.…”

Microscopic mechanical properties and injection molding‐induced morphology on polypropylene rubber blend

“…Therefore, a chlorinated polyolefin (CPO) based adhesion promoter was used as an intermediate binder, which penetrates into the substrate. The depth of penetration was affected by a content of elastomers in the substrates and organic solvent in the paint 1. Adhesiveness between substrates and paints was generally evaluated by a 180 degrees peel test, in which the peel strength was increased with adding an elastomer 2.…”

“…The depth of penetration was affected by a content of elastomers in the substrates and organic solvent in the paint. 1 Adhesiveness between substrates and paints was generally evaluated by a 180 degrees peel test, in which the peel strength was increased with adding an elastomer. 2 An adherence improved by the presence of the elastomer domain was explained by energy dissipation occurred during the rubber deformation.…”

Imaging the Interfaces of Conjugated Polymer Optoelectronic Devices

“…has been shown to improve the image contrast. [45][46][47] However, staining has been shown to introduce imaging artifacts. [48] For our purposes, we define the area bounded by bulk polymer signature and crystalline cathode material as the polymer-cathode interface, i.e., PFN + Br -/Al, which in this case is approximately 10 nm thick.…”
