Outline of Final Research Achievements

Newly prepared D-gluconamide derivatives containing a peptide moiety were examined for rust prevention effect on the iron surface. The antirust effect of the gluconamide derivatives was superior to those of the ammonium amphiphiles that contained the same peptide moiety. This result means that the gluconic acid head group should strongly bind onto iron surface by plural hydroxide groups. The surface treatment in order to prevent corrosion of metal has been achieved by use of mineral oil or coating materials such as paint. Compared with the conventional method, the rust prevention by means of the supramolecular material here used gluconamide derivative is unsuitable for large surface area, but convenient for micro- or nano-scale area, because its protective film possesses a very orderly molecular arrangement and should be theoretically effective even if the film possessed monomolecular thick.
