RESEARCH PROJECT

I am currently studying the adsorption of polymethacrylic acid to the carbon tetrachloride/water interface. I have determined the effects of specific polymer isomer, solution pH, and salt composition on polymethacrylic acid interfacial properties. Techniques used include vibrational sum frequency spectroscopy, pendant drop interfacial tension method, and the Wilhelmy plate interfacial tension method.
