Modifications of Paper Surfaces with Composite SiOx/Polymer Coatings
Abstract:
The composite SiOx/polymer films are deposited as a top-coatings onto the paper substrates by radio frequency (RF) reactive magnetron co-sputtered two targets, silica and dicyclopentadiene dioxide cured with maleic anhydride (DCPD/MA).The samples prepared by changing PSiO2 /PDCPD/MA, the ratio of RF powers density delivered to the individual target from 0.1 to 10 so as to prepare different SiOx content coatings. The wettability, mechanical properties, color reproduction printability, chemical characterization of the coatings are discussed in this paper, using contact angle measurements, electronic tensile testing machine, off-set printing test and FTIR. The static contact angle of water ranges from 129.7 to 90.7 o and tensile performance has improved significantly as the ratio of RF powers density change from 0.1 to 10. The ink density and depth of color during off-set printing are visually improved by using papers with hydrophobic surfaces coated composite films.
