摘要：
Neutron reflectivity measurements of thin films of electropolymerised poly(pyrrole) show that swelling of these insoluble polymers does occur following vapour adsorption. The variation in swelling found for different vapours is correlated with corresponding changes in polymer conductivity and mass of adsorbed vapour. This correlation suggests that hydrophobic and hydrophilic vapour species adsorb into regions of the membrane with different solvating environments (C) 2000 Elsevier Science B.V. All rights reserved.
