Biodegradable shape-memory material and method |
| abstract |
A biodegradable material with shape retention ability may be prepared using a process that includes (a) dissolving a polymer that in a first solvent to obtain a first solution; (b) dissolving a poly-N-vinyl lactam (e.g., polyvinyl pyrrolidone (PVP)) in a second solvent to obtain a second solution; (c) mixing the first solution with the second solution to obtain a liquid mixture; and (d) preparing the biodegradable material using the liquid mixture in an electrospinning process. The polymer may include a copolymer of lactide and caprolactone, where the lactide preferably includes L-lactide. The first solution may be an aprotic solvent, preferably ethyl acetate. |
