Supplementary Material

We present in supplementary material the attribution of peaks obtained from spectroscopy FT-IR coupled to termogravimetry (TG) comparing the results with peaks attribution in literature which is showed in Table S1. When evaluated the results obtained from TG/FT-IR for the different reduction times of gold nanoparticles, was necessary the study of relative intensity to compare the difference on composition of the natural rubber in terms of incorporation of gold nanoparticles. This study was realized by comparing the relation between the areas measured under the peak of each compound evaluated and the area from a standard peak. Then each measurement obtained to different reduction time of gold nanoparticles is showed in Table S2. The Figure S1 show the evaluation of the aqueous solution after insert natural rubber membranes during 120 min. at 80°C. This tests was implemented to evaluate the compounds released from natural rubber in solution under same conditions of the synthesis.
