摘要
A hydrogen bonding interaction is formed and broken between N of the pyridine ring and H–N of urethane in the PEG4000–MDI–BIN polymer due to the deprotonation and protonation of pyridine rings by simply changing the pH value of the external environment, and can reversibly switch both the shape memory and drug release.
