Compositions for reducing friction or stiction of a surface, methods and articles comprising the same

A method of decreasing at least one of friction or stiction of a surface, the method comprising:

• applying to the surface of a material, a composition comprising:
• a first part comprising:
• (a) at least one organosilane;
• or
• (b) a combination of at least one organosilane and at least one organophosphorus, and
• a second part comprising at least one polymer,
• wherein (a) or (b) of the first part is configured as an attached layer on the surface, and the at least one polymer of the second part is adjacent to the said attached layer,
• wherein the first part comprises at least one organosilane comprising only leaving groups and at least one organosilane comprising at least one non-leaving group, wherein the weight ratio of silanes with only leaving groups to silanes with at least one non-leaving group ranges between 1 to 100 and 10 to 1, and
• wherein the first part and the second part of the composition are found in an amount sufficient to decrease friction, stiction or both, of the surface relative to the surface in untreated form.

An article comprising:

• at least one surface having a surface treatment thereon, said surface treatment having a composition comprising:
• a first part comprising:
• (a) at least one organosilane;
• or
• (b) a combination of at least one organosilane and at least one organophosphorus, and
• a second part comprising at least one polymer,
• wherein (a) or (b) of the first part is configured as an attached layer on the surface, and the at least one polymer of the second part is adjacent to the said attached layer,
• wherein the first part comprises at least one organosilane comprising only leaving groups and at least one organosilane comprising at least one non-leaving group, wherein the weight ratio of silanes with only leaving groups to silanes with at least one non-leaving group ranges between 1 to 100 and 10 to 1, and
• wherein the composition is found in an amount sufficient to decrease friction or stiction of the surface relative to the surface in untreated form.
