Model artificial interphase samples consist of three different photopolymers deposited on a 2 cm x 2 cm PVC support (EMS Plastic Slides, Electron Microscopy Science). Prior to deposition, the plastic support was cleaned with an aqueous Alconox solution, rinsed with deionized water, and then dried in a stream of nitrogen, followed by air plasma cleaning for 2 minutes. To create the three photopolymer layers, first a PETMP-TATATO layer (S) was spin-coated onto the support at 1500 rpm for 30 seconds. This layer was then exposed to 365 nm UV light for 30 minutes to crosslink the polymer, followed by a 30-minute thermal annealing process at 65 °C. Readers should note that the thick, glassy S layer is considered the substrate in this study, rather than the plastic support material, which we did not further characterize. Subsequently, a toluene solution of PETMP-APE (I) was spin-coated onto the S layer at 4000 rpm for 30 seconds. This layer was also exposed to UV light for 30 minutes to induce crosslinking, followed by a 30-minute thermal annealing process at 65°C. Lastly, a TMPMP-APE solution (M) was spin-coated onto the previous layers at 1000 rpm, and then exposed to UV light for 30 minutes.
