Preparation of the samples included the following steps, surface modification of the substrate, polymer film deposition, thermal annealing, and selective degradation of the PLA phase, as illustrated in Fig. 4.1. The PLA removal does not alter the copolymers morphology and is comparatively easy, whereas the substrate choice, the surface modification, and thermal annealing protocol decisively influence the copolymer self-assembly behavior as will be discussed in the context of polymer phase separation [2,3]. The vast possible parameter space of the latter two preparation steps, combined with the numerous copolymers, presented a real challenge.
