A slip of the tongue : tribology of soft surfaces and complex lubricants
Nothing starts and nothing stops without friction. Moving body parts, operating a vehicle and orally processing food, all require a specific degree of friction and lubrication. Soft surfaces and biolubricants are known to exhibit complex and unexpected frictional or tribological behavior. In this thesis, we aim to uncover the most important parameters influencing soft tribology. To this extent, we use four different tribometers equipped with a range of surfaces including hydrogels and elastomers with different degrees of (3D-printed) roughness. We ultimately show that for all surface and lubricant combinations, specific frictional behavior occurs depending on the effective gap size.

| Summary: | Nothing starts and nothing stops without friction. Moving body parts, operating a vehicle and orally processing food, all require a specific degree of friction and lubrication. Soft surfaces and biolubricants are known to exhibit complex and unexpected frictional or tribological behavior. In this thesis, we aim to uncover the most important parameters influencing soft tribology. To this extent, we use four different tribometers equipped with a range of surfaces including hydrogels and elastomers with different degrees of (3D-printed) roughness. We ultimately show that for all surface and lubricant combinations, specific frictional behavior occurs depending on the effective gap size. |
