Biomimetic polysaccharide nanocomposites of high cellulose content and high toughness.

摘要: Plant cell walls combine mechanical stiffness, strength and toughness despite a highly hydrated state. Inspired by this, nanostructured cellulose network is combined with an almost viscous polysaccharide matrix in the form of 50/50 amylopectin-glycerol blend. Homogeneous films microfibrillated (MFC) nanofiber content range 10-70 wt % are successfully cast. Characterization carried out dynamic analysis, field-emission scanning electron microscopy, X-ray diffraction, mercury density measurements. The MFC well dispersed predominantly oriented random-in-the-plane. High tensile high modulus very work fracture nanocomposite 70 MFC. reasons for this interesting combination properties include properties, favorable nanofiber-matrix interaction, good dispersion, ability to maintain its integrity strain at least 8%.
