菠萝叶纤维素超级微晶的制备及其结构特性的研究

Preparation and characterization of super microcrystalline from Pineapple leaf fiber

  • 摘要: 对菠萝叶纤维分别通过NaOH、HNO3、HCl进行预处理,然后用64%H2SO4水解,运用扫描电镜、透射电镜、Zeta电位-粒度分析仪、红外光谱和X射线衍射对其结构与特性进行表征。结果表明,可制备出长度分布为300700nm,直径分布约为2050nm的棒状菠萝叶纤维素超级微晶;与原纤维素相比,菠萝叶纤维素超级微晶的晶型仍为纤维素I型,但结晶度由57.8%增加到82.7%。 

     

    Abstract: Pineapple leaf fiber was pretreated by sodium hydroxide, Nitric acid, Hydrochloric acid and hydrolyzed by 64% Sulfuric acid, super microcrystalline cellulose was gotten.The structure and properties of microcrystalline cellulose was characterized by Scanning electron microscopy ( SEM) , Transmission electron microscopy ( TEM) , Zeta potential and particle size analyzer、Fourier transform infrared chromatography ( FTIR) and X- ray diffraction ( XRD) .The results showed that the length and diameter distribution of super microcrystalline cellulose was 300700nm and 2050nm.The type of super microcrystalline cellulose was cellulose I, degree of crystallization was rised from 57.8% to 82.7%.
