Electrical Properties of Schiff Base Salts.

Abstract

An electromagnetic evaluation was made on a series of Schiff Base Salts produced by Hoffmann-LaRoche Inc. The evaluation included standard and nonstandard tests in an attempt to determine time or physical condition dependent phenomena. The results were not successful in detecting a loss capability which would make these salts useful as a passive radar absorber in a coating or other material system. As a result of this evaluation, the iodine ion was identified as a potential source of electromagnetic loss. This was further investigated in a series of starch iodine compounds. The first set demonstrated an increase in the loss for an iodine concentration of about 6.5%. A second set of starch iodine compounds was produced with iodine concentrations more closely grouped around 6.5%. Tests on this set confirmed a peaking of the loss for iodine concentrations in the range of 6.5% to 7%. The level of the loss factor was such that electromagnetic absorption could be obtained in a material combination containing these iodine compounds. This was not attempted since additional characterization of the starch iodine was required. jg p.3
