Randomized trial examines wetting behavior of specific copolymers on modified surfaces, indicating distinctive interactions.
Key Points
This study aims to investigate the wetting behavior of A-block-(B-random-C) copolymers on surfaces modified with corresponding B-random-C copolymers.
Two sets of A-block-(B-random-C) BCPs were synthesized using thiol–epoxy click chemistry involving TFET and either 2MP or MTG.
Surface modifications were made with B-random-C copolymers to analyze interfacial interactions and surface energies using scanning electron microscopy.
Composition ratios φ1 and φ2 were determined to achieve equal surface energies for BCPs and substrates, respectively.
For the 2MP and TFET thiol pair, the φ1 and φ2 values leading to equal surface energies differ significantly.
A similar difference in φ1 and φ2 values was observed for the MTG and TFET thiol pair.
For Δγsub = 0 with MTG and TFET, two distinct φ2 windows were identified, affecting wetting behavior.
