摘要
The effect of two model adjuvants (benzyl benzoate and benzyl alcohol) on the structure and dynamics of three Pluronic triblock copolymers (P85, P105 and F127) was studied using small-angle neutron scattering and pulsed-field gradient NMR. The two adjuvants studied have different aqueous solubilities. It was found that both adjuvants promoted the micellisation of the Pluronic block copolymers. In addition they lead to a swelling of the micelles, as shown by small-angle neutron scattering. From the pulsed-field gradient NMR results it was possible to determine the amount of adjuvant bound to the micelles. Crown Copyright (C) 2010 Published by Elsevier Inc. All rights reserved.
