Enhancement of polymer interfaces, especially in amorphous-amorphous polymer pairs, via the addition of a copolymer has received extensive attention in the past years. However, the fundamental studies on the reinforcement of the interface in semi-crystalline polymer pairs are very limited. Several papers were reported recently, which are focused on the only effect of chemical structure, i.e. the formation of copolymers at the interface on the interfacial fracture toughness of semicrystalline polymers. In the semicrystalline polymer pairs, not only the formation (areal density and chain length) of copolymers at the interface but also the crystalline microstructure of semicrystalline polymer will play important roles in determining the interfacial properties. In this work, we focused on the adhesive joint system of crystalline syndiotactic polystyrene (sPS)/ tethered polystyrene (PS) chains on silicon substrate. The dependence of interfacial properties on the structure of PS brushes has been systematically investigated. |
