본문내용

Synthesis ( I )
Physisorption
▪ Absorption of block copolymers onto a substrate
▪ One block interacts strongly with the surface and the other block forms the brush layer
▪ Disadvantage
: thermal instability due to the non-covalent nature
: poor control over polymer chain density
: complications in synthesis of suitable block copolymers.

Synthesis ( II - 1 )
Covalent attachment 1
▪ tethering preformed end functionalized polymer chains to a suitable substrate under appropriate conditions
▪ Disadvantage : low grafting density and low film thickness
