摘要 |
Hollow polymeric structures with unique morphologies are manufactured with a rotational spinning technique wherein phase separation of soluble solutions is induced within a filled mold as it is rotated. As phase-separation occurs, an increase in density of one phase results in sediment at a periphery under centrifugal forces and after or during sedimentation, gelation of phase-separated particles fixes a tube morphology. By controlling the rotational speed and the formulation chemistry, the tube dimensions and wall morphology can be manipulated. The method requires small quantities of starting material, permits multi-layering of tubes, is applicable to diverse polymers and results in highly diffusive hollow structures while maintaining good mechanical strength. |
