摘　　要：为应用高效、绿色超临界CO_(2)流体技术制备性能优良的保健类粘胶织物,通过负载不同极性药物烟酰胺、白藜芦醇制备粘胶织物,采用扫描电子显微镜、红外分光光度计、X射线衍射仪、热重差热综合分析仪、万能材料试验机表征和分析经处理后粘胶织物微观结构和宏观性能变化。结果发现:2种药物在粘胶纤维表面的分布形态均为小颗粒,相较白藜芦醇,烟酰胺在纤维表面的分布量更多;2种药物的负载均使得纤维分子链间氢键强度有一定下降,但并未改变其化学结构;极性更强的白藜芦醇对纤维结晶区的影响更加显著,负载2种药物后,粘胶纤维结晶度从41.37%分别下降至29.28%、23.37%;2种药物的负载使得粘胶纤维热降解性能均有轻微下降;药物的负载并未改变粘胶织物拉伸性能。Objective It is reported that supercritical CO_(2) fluid(SCF-CO_(2))can solubilize many drugs and carry them onto the polymer matrices,which allows to process with thermosensitive drugs and it enables to recover a final impregnated implant free of any solvent residue just by depressurization.Therefore,SCF-CO_(2) can be used to process functional viscose fabric.To achieve good drug loading performance,it is necessary to study the structure and property of different drugs-loaded viscose fabrics impregnated by SCF-CO_(2).Method Viscose fabrics loaded with different polar drugs of nicotinamide,resveratrol were processed by SCF-CO_(2) at 80℃,20 MPa,90 min.Scanning electron microscope(SEM)was utilized to analyses the surface morphology of drug-loaded viscose fabric.Fourier transform infrared spectroscopy(FT-IR)was used to monitor the change of the chemical structure of viscose fibre.X-Ray Diffraction(XRD)was applied to measure the crystallinity of drug-loaded viscose fibre.Thermogravimetry(TG/DTA)and INSTRON was respectively utilized to analyse the thermostability and tensile property of viscose fibre.Results The results showed that the surface morphology of viscose fibre did not change after SCF-CO_(2) treatment,and Nicotinamide and resveratrol were observed on the fiber surface in the form of small particles,but the distribution quantity of nicotinamide was more than that of resveratrol.The loading drugs had no effect on the chemical structure of viscose fibre,but it weakened the interaction between viscose fiber molecular chains.As a results,SCF-CO_(2) impregnation showed a plasticizing effect on viscose fiber.After the treatment of the pure SCF-CO_(2) the crystallinity was virtually changeless,but after being loaded with nicotinamide and resveratrol the crystallinity of viscose fiber was decreased from 41.37% to 29.28%,23.37%,respectively.It was found that after the viscose fiber was treated with pure SCF-CO_(2),the aggregate structure did not change significantly.However,after loading nicotinamide and resveratro
