FIG. 6.

(Color online) Photographs of the surfaces of (a) the bare PC, (b) the acrylic resin-coated PC, and (c) the silica-based film deposited from the TMOS flow rate of 0.3 g/min on PC, and (d) the silica-based film deposited from the TMOS flow rate of 0.3 g/min on the acrylic resin-coated PC after the Taber abrasion test. The optical microscope photographs of these samples are added for detail comparison.

Tables

Generic image for table
TABLE I.

Deposition rate, hardness, and refractive index as a function of the TMOS flow rate. The sample deposited from the TMOS flow rate of 0.15, 0.2, and 0.3 g/min is denoted as TMOS0.15, TMOS0.2, and TMOS0.3, respectively.

Generic image for table
TABLE II.

ΔHz values, transparency before and after Taber tests, and film thickness of silica-based layers. The sample deposited from the TMOS flow rate of 0.15, 0.2, and 0.3 g/min is denoted as TMOS0.15, TMOS0.2, and TMOS0.3, respectively. Primer-coated PC is denoted as Pri-PC.
