1D hypo-crystals of stereo-irregular PMMA via fast solidification of aqueous solutions |
| 초록 |
We recently reported 1D hypo-crystalline stereo-irregular poly (methyl methacrylate) (1D hc-PMMA) with high crystallinity and long-range order in solid films via the rapid thermal quenching with support of entropy diluent (or chain-stretching agent) as well as extraordinarily extended conformation of PMMA chains in PMMA/benzoic acid binary melts. Here, quick and simple solution processing of 1D hc-PMMA from quaternary solutions with air spray-coating was presented. In quaternary solutions, solubility of PMMA in aqueous ethanol strikingly increases and PMMA chains were spontaneously extended, which implies that polymer solubility in cosolvent systems can be increased by using appropriate entropy diluent. Successful 1D hc-PMMA preparation supports the crystallization mechanism proposed in the previous work and suggests that other stereo-irregular polymers are able to have long-range order with similar approaches emulating fast solidification with entropy diluent. |
