Abstract
The plasma polymerization method was applied to prepare organic thin films from perfluorobenzene (PFB) which have good affinity to oxygen. The aggregation structures and permeation properties of plasma-polymerized thin films were investigated as functions of the magnitude of radio frequency (RF) power, monomer flow rate, substrate temperature and annealing time after deposition. The chemical and aggregation structures of plasma-polymerized films were investigated on the basis of thermogravimetric measurement, infrared absorption spectra and X-ray photoelectron spectra. The unsaturated bond or aromatic ring changed into the highly crosslinked structure composed of saturated bonds with increases in the magnitude of RF power, substrate temperature and annealing time and also with decrease in the monomer flow rate. The magnitude of the separation factor through plasma-polymerized PFB (PPFB) films deposited on Millipore increased with an increase in the degree of crosslinking. In order to prepare the heat-resistant PPFB film, PFB was deposited on porous ceramics. The magnitude of oxygen permeability coefficient through the PPFB film deposited under the conditions of an RF power of 100 W, a substrate temperature of 573 K and annealing time of 5 h remained almost constant at about 2.8×10−8 cm3 (STP) cm−1 s−1 cmHg−1 from 283 to 573 K, and also, the separation factor gradually decreased from the magnitude of 4.5 at 283 K with an increase in temperature.
