Abstract
We provide the first experimental evidence for a transition from a "pancake" to a "brush" configuration for end-adsorbing polymers at the solution-solid interface. This transition, predicted earlier by Alexander, is a consequence of the competition between adsorptions by the backbone and the end-groups. It occurs when polymer pancakes start to overlap each other. The competition then drives some backbones into solution to form brushes. The transition region varies with molecular weight but does not vary with the end-group's adsorption strength. The thickness of the polymer layer, however, increases with the increasing end-group's adsorption strength.

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.

If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
