Claims28
A self-assembled monolayer (SAM) derived from an organophosphorus acid and containing a betaine polymer segment, wherein at least one organo group of the organophosphorus acid is substituted with the betaine polymer segment, and wherein the betaine polymer segment is derived from a betaine-containing monomer of the structure:
- where R1 is hydrogen or methyl;
- A is oxygen or —NH—;
- R2 is ethylene or propylene;
- R3 and R4 are alkyl;
- B is N or P;
- n is an integer of 1 to 4;
- and X− is SO3 or CO2−.
A substrate having adhered directly or indirectly through an intermediate organometallic layer to a surface of the substrate a self-assembled monolayer (SAM) derived from an organophosphorus acid, wherein phosphorus acid groups of the organophosphorus acid are adsorbed on the substrate surface and organo groups of the organophosphorus acid extend outwardly from the substrate surface and at least one of the organo groups is substituted with a betaine polymer segment, and wherein the betaine polymer segment is derived from a betaine-containing monomer of the structure:
- where R1 is hydrogen or methyl;
- A is oxygen or —NH—;
- R2 is ethylene or propylene;
- R3 and R4 are alkyl;
- and B is N or P;
- n is an integer of 1 to 4;
- and X− is SO3− or CO2.
A self-assembled monolayer (SAM) derived from an organophosphorus acid and containing a betaine polymer segment, wherein at least one organo group of the organophosphorus acid is substituted with the betaine polymer segment, and wherein the betaine polymer segment is derived from [2-(methacryloyloxy)ethyl]dimethyl-(3-sulfopropyl)ammonium hydroxide.
