Summary:The pyroelectric effect in Langmuir-Blodgett (LB) alternate layer
films of 22-tricosenoic acid and 1-docosylamine and films of an
organo-ruthenium complex (ruthenium
(η5-cyclopentadienyl)-(b triphenylphosphine)
4-heptadecoxybenzonitrile hexafluoro-phosphate) is reported. Methods of
increasing the pyroelectric response and thermal stability of the films
are discussed. Values of the quasi-static pyroelectric coefficient as
high as 17 μCm-2 K-1 have been achieved. The
figures of merit of these films incorporated in a room-temperature
thermal imaging device are presented, one of which is in excess of those
for VDF/TrFE copolymer films
