Abstract
Amphiphilic diblock-copolymers (DC) of (2,3,4,5,6)-pentafluorostyrene and 2-hydroxyethyl methacrylate were prepared for the first time by two-step reversible addition–fragmentation chain transfer (RAFT) polymerization. The morphology of films of diblock-copolymers that have a composition close to equimolar was studied by transmission electron microscopy. The observed microphase separation and formation of spherical nanodomains is not typical for equimolar diblock-copolymers and seems to result from hydrogen bonding between the hydroxyl and carbonyl groups (OH···OH and C=O···HO) in poly(2-hydroxyethyl methacrylate) blocks. Obviously, it is the ability of diblock-copolymers to self-organization is the cause of formation of fabric coatings with low surface energy (γ = 11.9 mJ/m2) and relatively large water contact angles (θН2О = 120±6°) and diiodmetane (θCH2I2 = 93±2°).
