Synthesis of polymer hollow spheres with single holes has been a challenging task in materials science. In this work, polyurethane (PU) hollow microspheres with size tunable single holes were fabricated through a facile self-assembly−diffusion process. Firstly, the as-synthesized PU polymers were di...
