Abstract
A method of making a razor blade by forming a cutting edge on a substrate having an outer bonding surface. A first self-assembled monolayer having a non-fluorinated organic material is deposited on the outer bonding surface of the substrate.
Claims17
A method for making a razor blade, the razor blade comprising a first self-assembled monolayer (SAM) and a second SAM directly deposited on the first SAM, the method comprising:
- forming a cutting edge on a substrate having an outer bonding surface;
- depositing the first SAM comprising a non-fluorinated organic material on the outer bonding surface of the substrate, wherein the non-fluorinated organic material is an organosilane, wherein the organosilane is a mixture of compounds having the following general formula:
- SiRnXm
- in which R is an alkyl group;
- X is a leaving group selected from a chloride, an alkoxy, or a hydride;
- n=1-3;
- and m=1-3;
- n+m=4 and the alkyl group(s) R may be substituted or unsubstituted, linear or branched, saturated or unsaturated and identical alky groups or different alkyl groups;
- and
- depositing the second SAM comprising a non-fluorinated organic material directly on the first SAM.
A method for making a razor blade, the razor blade comprising a first SAM and a second SAM directly deposited on the first SAM, the method comprising:
- forming an outer bonding surface on a sharpened cutting edge of a razor blade by depositing a first material on the sharpened cutting edge;
- treating the outer bonding surface to form a treated outer bonding surface;
- depositing the first SAM comprising a non-fluorinated organic material on top of the treated outer bonding surface;
- and
- curing the first SAM to form a cured first SAM, wherein the non-fluorinated organic material is an organosilane, wherein the organosilane is a mixture of compounds having the following general formula:
- SiRnXm
- in which R is an alkyl group;
- X is a leaving group selected from a chloride, an alkoxy, or a hydride;
- n=1-3;
- and m=1-3;
- n+m=4 and the alkyl group(s) R may be substituted or unsubstituted, linear or branched, saturated or unsaturated and identical alky groups or different alkyl groups;
- and
- depositing the second SAM comprising a non-fluorinated organic material directly on the cured first SAM followed by curing the second SAM.
