| Outline of Final Research Achievements |
Stress sensing coating which is used for local stress measurement in high spatial resolution of micormeter using a microscopic Raman spectroscopy was developed. In the stress sensing coating carbon nanotubes (CNTs) were dispersed with oriented in three different directions in order to detect stress components separately. To suppress in reaggregation of CNTs a UV-curable resin or a cellulose which acts as a dispersing agent were employed for matrix.
The obtained results are,
1. Dispersion of CNTs can be evaluated quantitatively by mapping distribution of the components using a microscopic Raman spectroscopy, even though CNTs were embedded in matrix resin. 2. By application of alternating electric field or squeezing by a blade CNTs can be orientated and their orientation can be controlled. 3. Raman shift from the film with oriented CNTs varied in proportion to the applied strain, so the film proved to act as a stress sensor.
