Abstract:
22-t ricos enoic acid ( 22-TA) Langmuir-blodgett ( LB) f ilm has been studied many times in pyroelect ric thermal imaging. T hough it has many andvantages the pyroelect ric thermal imagerneeds, it s st abit it y is not very good. T his paper present s the XPS spect ra of 22-TA pow er and LB films befor e and after annealling, and g ives out the x-ray litt le-ang le dif fr act io n spect ra of 22-TA LB f ilms. T he vesnlt s indicate that the 22-T A molecule str ucture and the LB f ilm crystall ine st racture chang e w ith temperature and t imes. T he reas o ns of these changes are discussed. T he results w o uld lead us to eng ineer pyro electric f ilms molecularly to be more stable and her ce more useful.
