| Popis: | The shape/temperature memory phenomena based on melting in unmodified thermoplastic poly-ɛ-caprolactone (PCL) (i.e., without chemical-cross-linking) were investigated systematically. Effects of factors, such as, deformation method (uniaxial tension/compression, indentation), deformation temperature, sample size, and heating method, on the shape memory effect were evaluated. Based on these results, the underlying mechanism for the shape memory effect in chemically un-crosslinked PCL (based on melting) is proposed. |
