选用真菌合成了丝状微米真菌纤维素,通过扫描电子显微镜（SEM）、红外光谱（FT-IR）、固体核磁共振（CP/MAS 13C NMR）、X射线衍射（XRD）等分析方法对真菌产生的纤维进行了微观形貌和化学结构表征。SEM结果表明由真菌产生的纤维均为微米级,成条形纤维状,具有清晰的三维网状结构;FT-IR结果表明真菌纤维中可能含有—OH、—C—O—C、—CH2、—NH2等特征官能团,与棉花纤维素所含特征官能团相似;将真菌纤维的13 C NMR和XRD与天然纤维素以及细菌纤维素比较,发现真菌纤维的化学位移与细菌纤维素相似,含有较高的I晶型纤维素和非晶体化合物。真菌纤维有可能被用作模板剂或聚合物增强方面。

Silk-like fungus fiber with micrometer size was prepared via fungus method.SEM,FT-IR,CP/MAS 13C NMR and XRD were used for the microcosmic features and chemical structure analysis of the obtained fungus fiber.Result of SEM indicates that the fungus fiber is silk-like within micrometer size（0.8μm）,which forms a distinct 3-D network.The result of FT-IR reveals that the fungus fiber contains —OH,—C—O—C,—CH2 and —NH2.Chemical shift of fungus fiber is similar with that of bacterial cellulose,together with high content of I-type crystal cellulose and non-crystal compounds.The characteristics of fungus fiber revealed its potential as templates and reinforced polymer material.
