Surface primer compositions and methods of use

A method for forming a coating on a surface of a substrate, the method comprises:

• 1) optionally, washing the surface of the substrate with a first solvent;
• 2) contacting the surface binding compound of the Formula I, optionally in a second solvent, to the surface:
• wherein:
• a is 2, or 3;
• m is 1, 2 or 3;
• n is 1;
• i is 1, 2, or 3;
• each EG is an end group independently selected from the group consisting of a CH2═CHC(O)—, CH2═C(C1-3alkyl)C(O)—, CH2═CHC(O)O—, and CH2═C(C1-3alkyl)C(O)O—;
• each of SP1, SP2 and SP3 is a spacer independently selected from the group consisting of —O—, —C(O)—, —(CH2)q—, —OC(O)—, —CO2—, —NHC(O)—, —C(O)N—, —NC(O)—, —C(O)NH—, —NCH3C(O)—, —C(O)NCH3—, —(CH2CH2O)p—, —CH2CH2—(CH2CH2O)p—, p is 1 and q is 1-6;
• Ar is an aryl group;
• each BG is —OH;
• provided that when -SP3- is —CH2— or —C(O)—, Ar-(BG)a is not 3,4-dihydroxyphenyl;
• 3) for a period of time for the compound of the Formula I to form a layer on the surface of the substrate;
• and optionally
• 4) washing the excess compound of the Formula I from the surface of the substrate with a sufficient amount of a third solvent to remove excess compound from the surface.
