| Outline of Final Research Achievements |
Poly(lactic acid) attracts interest as eco-friendly and biocompatible polymer. The purpose of this study is the characterization of the structure and physical properties of poly(lactic acid) gel formed by complex crystals of poly(lactic acid) and some solvents.
The complex crystals of poly(lactic acid) and some solvents form nano-fibers with diameters of about 100 nm, and the fibrous structure presents the solvent flow and induces the gelation. Once the nano-fibrous structure is formed by the complex crystals, the nano-fibrous structure and the gel condition are preserved even after changing the complex crystals to another crystals form of poly(lactic acid). This characteristics enabled us to prepare poly(lactic acid) gels with higher thermal stability by forming the nano-fibrous structure formed by the complex crystals and heating the gel to change the crystals to another crystals form with higher melting temperature.
