Novel bionic surface modification methods

OBS! ANSÖKNINGSTIDEN FÖR DETTA EXJOBB HAR LÖPT UT.
Diploma work at Division of Surface and Corrosion Science, Royal Institute of Technology (KTH), and YKI, Institute of Surface Chemistry.

Aim
Development of novel bionic surface modification methods based on adhesion promoters.

Background
Surface engineering can be used to develop a wide range of functional properties, including physical, chemical, electrical, electronic, magnetic, mechanical, wear-resistant and corrosion-resistant properties at the required substrate surfaces. These techniques are use in a wide range of industries such as the automotive, aerospace, power, electronic, biomedical, textile, petroleum, petrochemical, chemical, steel, power, cement, machine tools, construction industries.
For surface functionalization surfaces often have to be pre-treated to increase their reactivity with for example etching. Simple non-etching dip-coating methods would prevent loss in mechanical strength caused by etching.
Bionics is learning from nature, i.e. the application of biological methods and systems found in nature to the study and design of engineering systems and modern technology.
This project will investigate the possibilities to develop methods of functionalizing surfaces inspired by the extraordinary adhesion ability of mussel feet protein.
The research program specifically aims at increasing the fundamental understanding of the adhesion properties and possibilities for functionalizing surfaces with molecules inspired by mussel feet protein. It will address scientific problems that have to be overcome in order to develop the general applicability of the concepts.

Work plan
Experiments will include adsorption, adhesion, surface analysis and advanced electrochemical measurements.
In addition to the experimental study, the diploma work will also consist of a literature survey, and writing of the diploma thesis. The project will start as soon as possible.
