Direct observation of dynamic interaction between a functional group in a single SBR chain and an inorganic matter surface

In the article  “Direct observation of dynamic interaction between a functional group in a single SBR chain and an inorganic matter surface” Ken-ichi Shinohara and Yuu Makida use atomic force microscopy (AFM) video imaging to closely investigate the behaviour of functionalized and unmodified styrene-butadiene rubber (SBR), as models for tire rubber, on mica surfaces.

“Using AFM video imaging, we tracked the behavior of individual SBR polymer chains on mica surfaces to reveal how polymer modification affects the interaction of SBR with mica surfaces. We measured the diffusion coefficients and spring constants of single SBR polymer chains for the first time, demonstrating that it is possible to parameterize the relationship between the molecular dynamic structure of a polymer and rubber properties of the vulcanized compound.”*

NanoWorld Ultra-Short Cantilevers (USC) for Fast-/High-Speed AFM  ( USC-F1.2-k0.15 ) were used

Snapshot AFM image of a fast-scanning atomic force microscopy (AFM) movie; X: 200 nm, Y: 150 nm, Z: 7.2 nm. Rate: 5.0 fps. (B) A snapshot of all-atom MD simulated structure of a single chain of carboxyl-functionalized SBR (CPK model) in n-octylbenzene as a solvent. Dynamic globular (ball-like) structures were formed partially in a SBR chain. The position of carboxyl group was indicated by an arrow. The backbone was displayed in purple. Solvent molecules are indicated by line model and hydrogen atoms are omitted for simplified to view. NanoWorld USC-F1.2-k0.15 AFM probes were used

NanoWorld AG introduces Ultra-Short Cantilevers for High-Speed Atomic Force Microscopy (HS-AFM)

Neuchâtel, February 19th 2014, NanoWorld AG today announced the official commercialization of six types of Ultra-Short Cantilevers (USC) dedicated for use in High-Speed Atomic Force Microscopy (HS-AFM).

USC-cantilever-3D-view-close-upHigh Speed Atomic Force Microscopy is a quickly evolving technique within the field of Scanning Probe Microscopy that enables the users of dedicated instruments and AFM probes to visualize dynamic processes at the single molecule level. (See also www.highspeedscanning.com).

After a very successful beta-testing phase six types of AFM probes for high speed scanning will be commercially available from now on.
