This paper aims to synthesize nanocomposites based in hydroxide salts intercalated with organic ultraviolet (UV) absorbent molecule for use in the lining of cables that could be apply in the electrical center. The synthesis procedure was performed using urea hydrolysis of Co (II) nitrate melts at 160 °C and its modification carryout in an oven at 90 and 120 °C in a simple process. The modified structure and thermal stability of the hydroxide salt with formula (Co(OH)1,7(PABA)0,3).0,443H2O were characterized by XRD, FTIR, TGA, Raman, DSC, UV-Vis, MEV. Its studies suggest that HNCo-AB may have potential application as a UV absorber, because it improves this property when mixing with polyethylene,when the UV spectra shows a big band that covered the region between 400-200 nm.
