Description

Stimuli-responsive physical hydrogels change their properties upon a small change of the environment and may be used as fast sensors, for drug delivery or for tissue engineering. In this work, we investigate the telechelic pentablock terpolymer P(n-BuMA-co-TEGMA)-b-PDMAEMA-b-PEG-b-PDMAEMA-b-P(n-BuMA-co-TEGMA) in dilute aqueous solution as a function of temperature and pH using small-angle neutron scattering (SANS), elucidating the core-shell structure and the conformation of chains in the shell.
