Md. Foster et al., STRUCTURE AND STABILITY OF LANGMUIR-BLODGETT-KUHN MULTILAYERS CONTAINING HAIRY-ROD COPOLYMERS, Macromolecular symposia, 87, 1994, pp. 35-43
The microstructure and thermal stability of Langmuir-Blodgett-Kuhn mul
tilayers containing rod-like polyglutamate copolymers having flexible
aliphatic side chains have been studied with x-ray and neutron reflect
ometry. Upon annealing at 84-degrees-C the multilayer structure change
s in a manner which is dependent upon the degree of orientation of the
rod-like backbones and therefore upon the flow dynamics of the deposi
tion. A sample deposited with a highly convergent flow loses the bilay
er structure induced by deposition, whereas samples with less highly a
ligned backbones may not undergo this relaxation as readily.
