Abstract
The enhancement of adhesion for Cr film on polycarbonate (PC) substrate with electron irradiation treatment was considered. The electron treatment changes the contact angle of the PC substrates. As increase the electron energy from 300 eV to 900 eV, the contact angle decreases from $90^{\circ}$ to $60^{\circ}C$. It is supposed that electron treatment changes the chemical property of PC substrate into hydrophilic one. The micro surface roughness was also affected by electron treatment. The PC substrates irradiated with intense electron beam of 900 eV show the rougher surface than those of other PC substrates. Cr thin films deposited on the PC substrate treated with electron irradiation at 900 eV show the higher adhesion than that of the Cr thin film deposited untreated bare PC substrates.
