Abstract

Pulsed laser deposition of complex, chemically sensitive polymers using tunable, picosecond infrared laser excitation has shown great promise for producing films of these materials appropriate for a wide variety of sensor and coating applications. Fourier-transform infrared spectra of the bulk starting polymers and those of the deposited thin films are nearly identical, verifying that the short-range order and chemical functionality of the polymers are preserved during the process. Gel permeation chromatography and mass spectrometry have been used to characterize the polydispersity of the mass distribution; here the results are mixed, with the mass distributions of some poly-mers being preserved while others show significant bond scission. Most recently, we have demonstrated that it is possible to coat cantilever structures with the polymer SFXA; the deposited polymer responds as desired when 'challenged' by appropriate chemicals.
