The hydrogen bond formed between drug (COOH) and PA-1 (COOH) was weaken by repulsive interaction using FT-IR and Raman spectra, and molecular transportation of PA-1 was elevated by dielectric spectroscopy. And COO- was verified as molecular basis of repulsion in PA-1 through brand-new peak appearance (α-carbon of COOH 77.22 ppm) of 13C NMR and 9% increased carbonyl content in XPS spectra. It had been more confirmed by enhanced conductivity of PA-1 with dielectric spectroscopy, EP
