Relationship Between Dynamic-Response of Surface to Environmental-Changes and Adhesive Property of Polyacrylate
Acrylate copolymer composed of octadecyl acrylate (OA), 2-ethyl hexyl acrylate (2-EHA), hydroxythyl acrylate (HEA), and vinyl acetate (VA) was synthesized. The copolymer was used to adhere polyethylene (PE) with T-type peel, strength 4.4 N/cm. The interfacial characteristics of copolymer and PE were investigated via ATR-FTIR, transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), and dynamic contact angle (DCA). Results show that apolar moieties of the adhesive enrich on the interface. Moreover, the time dependence of peel strength coincides with that of enrichment in nonpolar moieties on the interface.
