【摘要】 通过NaOH/尿素/硫脲/水新型溶剂溶解原生木浆纤维素得到纤维素溶液,并与丝素溶液混合制备纤维素-丝素复合膜。利用扫描电镜、红外光谱、X-射线衍射对复合材料的结构进行表征。SEM结果表明复合材料表面粗糙,比表面积较大,可以作为潜在的生物医用材料。IR和X-衍射结果表明再生纤维素与丝素分子之间存在着强烈的氢键作用,且二者相容性较好。更多还原

【Abstract】 The cellulose-silk fibroin composite film is prepared by mixing cellulose solution dissolved primary wood pulp in solution containing of NaOH/urea/thiourea/water and silk fibroin solution.The composite film is characterized by scanning electron microscope(SEM),Fourier transform infrared spectrometer(FT-IR),X-ray diffraction(XRD).SEM shows the surface of the composite is uniform and rough.The as-prepared composite film may be a potential biomedical material.The results of IR and XRD show that composite film is composed of cellulose and silk fibroin molecules and exists an interaction including hydrogen bond between the molecular of cellulose and silk fibroin.更多还原
