Noncovalent grafting of polyelectrolytes onto hydrophobic polymer colloids with a swelling agent |
| 초록 |
Often it is not feasible to graft hydrophilic polymer stabilizers covalently to polymer colloids as reactive binding sites are either not available or would interfere with the functional properties. Here, we present facile, general and scalable physical protocols for permanent noncovalent grafting of polyelectrolytes to hydrophobic polymeric nanoparticles with chemically inert surfaces using polyurea and polyurethane polymer nanocapsules as examples. The polyelectrolytes are adsorbed and physically entangled within a partially liquefied polymer surface upon adding a small amount of organic solvent as a swelling agent. |
