摘要: The biomolecule-inorganic hybrid materials are potential candidates for low infrared emissivity mate- rials due to the combined functionalities of biomole- cules and inorganic components. In this study, we describe a facile approach fabricate DNA/layered double hydroxides (LDHs) nanohybrid by coassembly exfoli- ated Ni-In LDHs nanosheets with DNA. assembly progress, exfoliated DNA dif- ferent initial DNA/LDHs mass ratio were mixed together, intercalated was obtained only when input is B0.3 mg/ mg. structure morphology as-fabricated characterized X-ray diffraction (XRD), UV-Vis absorption spectra, Fourier transform (FT-IR) thermogravimetry (TG), scanning electron microscopy (SEM), transmission (TEM). results indicate that reassembled product has layered structures incorporated biomolecule. expanding d003 = 2.6 nm confirms intercalation mole- into interlayer. helix chain oriented parallel basal plane host layer forming ordered sandwich structure. value then investigated. It found values significantly reduced DNA, which may be attributed synergistic effect interfacial interaction between bio- molecule layers reinforced construction
