Here are my questions I hope you will help me You can see the file attached it is very brief..

•First Slide Showing the ATR Spectrum for absorbance for coated polymer with different concentrations (In miliMolar) on Copper samples

•Second Slide is showing the ATR Spectrum after the annealing was done at 100C for one hour while the blue curve in the second slide is showing just the blanket copper with no coating on it after annealing at same temperature

•Q1, why the spectrum in both cases after coating and after annealing is showing the drop in intensities of the peaks for higher concentrations of polymer what is meant by that? Although spectrum is similar in all the cases not much changing even not really in the position of peaks

•Q2, Polymer coated is derivative of benzene. Although after annealing, on sample it is giving the same contact angle of around 88 degrees and even higher same as that of blanket Cu with no coating But why then it is showing some peaks in finger print region if we assume that after annealing the coating is decomposed or gone.

•Is OH group present between 2500-3300 on coated ones(Slide 1) and also an annealed one (Slide 2) , How can I differentiate? On which bases? Remember it is an aromatic compound.

•Your Answers are appreciated
