将微晶纤维素溶于离子液体中,加入不同质量的聚乳酸,配制成共混溶液并成膜。通过红外光谱对其结构进行测定,证明共混物制备成功。X-衍射、SEM及DSC测试结果表明,共混物之间具有较好的相容性,当微晶纤维素与聚乳酸的质量比为60：40时共混效果较好,较易成膜,且二者的结晶过程得到互相促进,结晶完美度及晶体尺寸提高。同时,DSC测试结果表明,不同质量比的纤维素-聚乳酸共混物具有不同的结晶度,且纤维素与聚乳酸的质量比为60：40时亦具有较好的化学及生物降解性。

The cellulose-polylactie acid blending membrane was prepared via mixed solvent method.Firstly, microcrystalline cellulose was dissolved in ionic liquid,and then a different quality of polylactic acid was added. Infrared spectroscopy（FTIR） determined that blending membrane was prepared successfully.According to the results of X-ray diffraction,SEM and DSC,the microcrystalline cellulose and polylactic acid showed good compatibility with each other.When the mass ratio of microcrystalline cellulose to polylactic acid was 60：40,the membrane was easily obtained.At the same time,the crystallization process was promoted,and crystallization degree and crystal size were also increased.The results of DSC also showed that different mass ratio of cellulosepolylactic acid membrane had different degree of crystallinity.When the mass ratio of microcrystalline cellulose to polylactic acid was 60：40,the membrane also had good chemical and biological degradation.
