Studies of long monodisperse normal alkanes have had a major impact on the field of polymer crystallisation and morphology. This proposal is part of a joint programme by the Universities of Durham, Sheffield, Sheffield Hallam and Nottingham, with the aim of extending the scope of these studies using our joint expertise in physical characterisation. The Durham group has already successfully synthesized a number of the alkanes necessary for the research proposed here.The insertion of chemical probes will allow the application of a broad range of experimental techniques to recently discovered lamellar structures, while the introduction of new molecular architectures will result in entirely new morphologies.For example, to investigate the relative stability of the semicrystalline (crystalline-amorphous) double layer and to produce new double- and triple-layer superlattices, different three-branch (Y-shaped) alkanes will be investigated. To complement SAXS and Raman LAM studies, two linear and one branched alkane have been end-capped with C12D25 labels for neutron scattering, NMR and IR experiments designed to probe the location, conformation, mobility and the environment of chain ends. This research will provide answers to a number of questions regarding chain folding, ciliation, the crystalline-amorphous interface, surface roughness, chain tilt, etc.
