摘要：
In this research, novel organic-inorganic nanocomposite films of Konjac glucomannan (KGM) and US were prepared by one-step synthesis. As-prepared films were characterized by IR, TEM and SEM. The results indicated that hexagonal US nanoparticles with the sizes of 10 to 100 nm were well dispersed in KGM. The infrared emissivities of the films were characterized by IR-1 infrared emissivity instrument. As results showed, the KGM/CdS nanocomposite films had significantly lower infrared emissivity (8-14 mu m), meanwhile when the size of KGM nanoparticles was between 10 and 20 nm and the mole ratio ofCdS to KGM was 1.2:1, the film got the lowest infrared emissivity value of 0.011, which would be attributed to the strong synergism effect existing between KGM and US nanoparticles.
