Polymer nanoparticles held together by non-covalent bonds in solution have incredible potential applications in the field of nanotechnology, due to the dynamic properties of the reversible bonds controlling the polymer conformation. Here we have synthesized a terpolymer composed of BMA as the self-complementary hydrogen bonding unit, and lauryl methacrylate (LMA) as a solubilizing unit within a methyl methacrylate (MMA) backbone by reversible addition-fragmentation chain transfer (RAFT) copolymerization. By switching the solvent to induce hydrogen bonding, we have devised a kinetic pathway to target the metastable nanoparticle state by inducing intramolecular collapse. We demonstrate that the change in the polymer conformation by applying thermal stimulus results in the macroscopic change of the polymer solution, providing an interesting possibility of controlling polymer solution properties. |
