Crystal orientations and structures of poly(ethylene-ran-vinyl acetate) films coated onto silicon substrates

The crystal orientations and structures of poly(ethylene-ran-vinyl acetate) (EVA) films coated onto silicon substrates to a thickness of 5–200 nm were investigated by performing isothermal crystallization of the films. Bulk-like isotropic crystal orientations and orthorhombic crystalline phases were...

Description
Summary:The crystal orientations and structures of poly(ethylene-ran-vinyl acetate) (EVA) films coated onto silicon substrates to a thickness of 5–200 nm were investigated by performing isothermal crystallization of the films. Bulk-like isotropic crystal orientations and orthorhombic crystalline phases were observed in films thicker than 50 nm. In the thinner films (
