Self-assembly of block polymer provides an unique platform for generation nanostructures with controlled size and morphology. It can be further enriched by introducing a homopolymer as an selective additive, which swells the corresponding microdomain and results in an increase in the domain size and often a transition to different phases. Here, we explored the effect of homopolymer addition in the polymerization-induced microphase separation (PIMS) process by adding polylactide homopolymer (PLA-OH) to the reaction mixture of styrene (S), divinylbenzene (DVB), a molecular chain transfer agent (CTA), and PLA-CTA. By varying the amount of PLA-OH, we will discuss how PLA-OH affects the domain size of the resulting cross-linked polymer consisting of a disordered bicontinuous morphology formed via the PIMS process, which leads to formation of porous polymers with 3D continuous pore structure with control over a wide range of pore size. |
