Nanostructured Polymer and Composite Particles: Mechanical Properties

Tildelt: kr 2,1 mill.

In Norway there is a renewed interest in extending the Ugelstad method based polymer particle technology to microsystem applications by producing nanostructured (conductive) polymer and composite particles. In these applications, the characterization, ana lysis and control of mechanical properties of the particles are of crucial importance to both the particle producers and end users. Unlike bulk materials, characterization of nanostructured polymer and composite particles possesses great challenges. Since an extremely small volume is involved, sample preparations face many difficulties. Not only new experimental facilities but also novel analyzing methods for measuring mechanical properties should be developed to address the critical deformation and failu re mechanisms. This project is initiated and backed by a group of Norwegian industry partners with strong motivations and clear demands. Successful execution of this project will have a major added value to the industrial partners. The most central R&D ch allenges in the project are: 1) To develop a nanoindentation based method suitable for characterization of polymer and composite particles where material inhomogenity and sphere geometry possess challenges and need special treatment. 2) To develop analyzi ng methods and mechanics models describing the deformation and failure mechanisms of nanostructured polymer and composite (porous) particles and taking material nonlinearity, properties mismatch, liquid crystal and polymer interaction and other effects in to account. 3) To establish a link between the mechanical properties and microstructures and further apply these knowledge to design particles of specific mechanical properties.
