Abstract

HEUSER, MARCIA; RIVERA, CLAUDIA; NUNEZ, CHRISTIAN  and  CARDENAS, GALO. CHITOSAN-COPPER PAINT TYPES AS ANTIFOULING. J. Chil. Chem. Soc. [online]. 2009, vol.54, n.4, pp.448-453. ISSN 0717-9707.  http://dx.doi.org/10.4067/S0717-97072009000400028.

A prototype of antifouling paints was prepared with a QS-Cu (I)-Fe (II) complex as a possible replacement for traditional antifouling paints, which contain a large concentration of copper, fnding them in an order of 10 - 30 % depending on the brand, and if it is water or solvent based. A Qs-Cu complex was prepared, with a solution at 3% with acetic acid, and then Fe2O3 was added to the solution. FT IR analysis was carried out, as well as analysis of the TGA at the Qs and the complex with Qs-Cu, and with the solution, three different paints were prepared. Those that varied volumen of diethylene glycol added to them. The analysis of the paints was carried out, once the paint was pervaded in a network of polyamide, through SEM with EDX and TEM, which was purchased with the commercial paints, water based and solvent based. One of the objectives is to be able to compare the coverage of the network with the commercial paint, and that of the complex QS-Cu. The results showed that the best paint obtained was paint #2, found to be similar to that pervaded with water based paint.
