|Title:||Tribological properties of thin functionalized polyethylene film on Si with chemical modifications||Authors:||Minn, M.
|Issue Date:||2010||Citation:||Minn, M.,Soetanto, Y.S.G.,Sinha, S.K. (2010). Tribological properties of thin functionalized polyethylene film on Si with chemical modifications.

ScholarBank@NUS Repository. https://doi.org/10.1115/IJTC2010-41111||Abstract:||A very thin functionalized polyethylene (fPE) film is successfully attached to Si substrate via a reactive benzophenone (Ben) layer. The presence of fPE promotes the wear durability of Si/Ben/fPE to 1000 cycles compares with 100 cycles of Si/Ben under 40 mN applied load and 500 rpm sliding speed. As an enhancement, perfluoropolyether (PFPE) is applied as a top mobile lubricant layer coated onto Si/Ben and Si/Ben/fPE and their tribological properties are evaluated under the same experimental conditions. A significant improvement in the wear durability is observed as Si/Ben/PFPE fails at 250,000 cycles and Si/Ben/fPE/PFPE does not fail till one million cycles. Si/Ben/fPE/PFPE can withstand the maximum applied load of 150 mN that provides the PV limit of 106.6 MPa ms-1.
