ZnS/Bacterial Cellulose/Epoxy Resin (ZnS/BC/E56) Nanocomposites with Good Transparency and Flexibility

ZnS/bacterial cellulose/epoxy resin (ZnS/BC/E56) nanocomposites with good transparency and flexibility were prepared and characterized. When the precursor Zn2+ concentrations were not more than 1 wt%, the size of the introduced ZnS nanoparticles was smaller than 50 nm and the distribution was homogeneous within the composites. Under the condition, outstanding transmittance more than 70% in the visible light was obtained. By incorporation of ZnS nanoparticles with excellent thermo-optic stability to the composites, the thermo-optic coefficient was obviously increased from −361 × 10−6 to −310 × 10−6 K−1. The good flexibility, optical and mechanical properties endow the nanocomposites potential applications in the flexible optoelectronic materials.
