Preparation of the controlled-release materials was carried out using essential oil from Thujopsis dolabrata var. hondae and synthetic L-LA (L-lactide) random copolymers as a base material using scCO2. The contents of oil into poly(L-LA) random copolymers at 75% of L-LA were the highest. The pressure of essential oil impregnated into poly(L-LA) random copolymers was the highest at 14 MPa. In the influence of temperature on impregnation, the amount of essential oil increased with increasing temperature. The mechanical properties (tensile strength, elongation and elastic modulus) of the copolymers impregnated with essential oil were evaluated. The tensile strength and the elastic modulus of poly(L-LA) fell by impregnation of the oil. It turned out that mechanical properties differ in a tendency by polymer. In the degradation test, the residual oil by degradation of copolymer was proportional to degradation rate, and the earliest copolymer of degradation had an early reduction of residual oil.

使用罗汉柏精油制备控释材料。使用 scCO2 和合成 L-LA（L-丙交酯）无规共聚物作为基础材料。 L-LA含量为75%时聚(L-LA)无规共聚物中油含量最高。精油浸渍聚(L-LA)无规共聚物的压力最高为14 MPa。在温度对浸渍的影响中，精油的量随着温度的升高而增加。评估了用精油浸渍的共聚物的机械性能（拉伸强度、伸长率和弹性模量）。由于油的含浸，聚(L-LA)的拉伸强度和弹性模量降低。可知机械特性因聚合物而有不同的倾向。降解试验中，共聚物降解后的残油量与降解速率成正比，且最早降解的共聚物残油量较早减少。
