Thermal stability up to 160 degrees C of monolayers of trichloro(octadecyl)
silane (TCOS) and cadmium stearate (CS) on solid substrates are examined by
using FT-IR transmission spectroscopy. The changes in wavenumbers and abso
rbances of CH2 stretching bands with temperature clearly demonstrate that t
he 1-layer LB film of TCOS on glass slides are considerably stable and resi
stant against heating, compared with that of CS.
