Influence of nanodiamond loading on properties of poly(vinyl alcohol) nanocomposite membranes

Popis výsledku v původním jazyce

Carbon nanomaterials are well-known for their unique physical properties. They have attracted interest as reinforcing fillers because of their superb mechanical properties. We report the excellent reinforcement properties of polymer nanocomposites by the incorporation of nanodiamond (ND). ND has been expected to offer polymer nanocomposites optimal properties because of its smooth surface and excellent optical, mechanical, and thermal properties, which can approach the values of single diamond crystal. We prepared advanced nanocomposites membranes based on poly(vinyl alcohol) (PVA) and ND in a single step using the solution casting method from aqueous medium and achieved the high dispersibility of ND in the PVA matrices. The thermal, mechanical and rheological properties of the membranes were investigated by means of thermogravimetry (TGA), dynamic mechanical analysis (DMA) and Ares G2 rheometer. The resulting nanocomposites had excellent properties derived both from ND and PVA. Thermal and mechanical properties increased dramatically with increasing ND content, indicating a strong interaction between ND and PVA. We anticipate that ND will be able to compete as a nano filler against conventional carbon-based nano fillers for polymer composites, and it is possible their reinforcement properties will be extended in the future.
