to the increasing environmental awareness, nanocellulose/natural
clay composites with improved
mechanical performance have attracted growing interest due to their
eco-friendly properties. In this study, hybrid films composed of cellulose
fibers (CFs) and imogolite nanotubes (natural aluminosilicate nanotubes)
were fabricated. We mainly studied the structure, density, and properties
of the hybrid materials. Specifically, the hybrid materials were characterized
by scanning electron microscopy (SEM), atomic force microscopy (AFM),
Fourier transform infrared spectroscopy (FT-IR), X-ray photoelectron
spectroscopy (XPS), thermogravimetric analysis (TGA), dynamic mechanical
analysis (DMA), a rheological test, and wide-angle X-ray diffraction
(WAXD). The mechanical properties of the hybrid materials were measured
by a tensile test, which demonstrated that the mechanical properties
of the hybrid films were considerably improved by the addition of
imogolite up to 1 wt %; meanwhile, the thermal–mechanical properties
of the hybrid film were also enhanced.
