Abstract

Molecular orientations and crystal structure of thin films of some basic esters on SiC natural surface and metal surface were studied by electron diffraction reflection method. Didecyl and didodecyl adipate films made from the evaporation of its benzol solution take no orientation but didodecyl sebacate film takes orientation and crystallizes in the 2-dimensional crystal with its long chain axis _??_ormal to the basal surface.<br> The built up films of the above three dibasic esters take always orientation. The structure of didodecyl sebacate crystal is orthorhombic with lattice constants a0=7.45±0.03Å, b0=5.01±0.031Å and similar to the n-paraffin. From the results, it is concluded that the dibasic ester molecule is straight and attacks at the methyl group with basal surface, not at C=O. Relation of the, orientations with lubricating properties was also discussed.
