Facile route to synthesis and morphology control of anionic waterborne polyurethane hollow microspheres via self-crosslinking reaction

摘要

Porous waterborne polyurethane (WPU) hollow microspheres were synthesized via a self-crosslinking reaction of WPU prepolymer terminated by 3-aminopropyltriethoxysilane (APTES). The microspheres with different morphologies were fabricated by changing the content of small molecules and hydrophilic groups.
