Abstract
The pin-on-disk wear rate of the Langmuir-Blodgett film of the Cd salt of 10,12-tricosadiynoic acid increases by a factor of five when the film is polymerized by UV light. It is proposed that this is an artifact of the Langmuir-Blodgett film since it is known that polymerization of the diacetylene function does not occur across the domain boundaries of the LB film. The wear particles of the polymeric film, therefore, occur in units of molecular domains in contrast to the single molecules of the monomeric salt of the diacetylene carboxylic acid. The increase in wear rate is due, therefore, to the increase in the molecular weight of the wear particle.
