Synthesis of Undoped CPs-Based BLNs

As already discussed, many a times, undoped CPs (those which are semiconducting in nature with optimum bandgap and optoelectronic properties) 

Soft Materials (CP, functionalized Graphene or -Fullerene derivatives, Graphene-Quantum/Carbon dots) (Electron acceptor) 

Interestingly, besides nature and concentration of blend phases, the presence of solvent and gentle annealing also plays important role in determining the final film micromorphology [228,238]. 

For example, controlled annealing of MDMO-PPV/PCBM blend films causes the differential phase crystallization. As a result, the PCBM single crystals grow gradually with annealing time and stick out of the film plane [428]. 

Nevertheless, it is important to point that, though the use of a compatibilizer (e.g., DBCs acting as a macromolecular surfactant and form a layer at the interface between the two homopolymers, thereby reducing the interfacial tension between the two domains and stabilizing the microscopic morphologies) can improve the phase stability, but it often result in micrometer to sub-micrometer size discontinuous (islands of minor phase in pool of major phase) dispersion of phases (as shown schematically in
