Nanocomposite materials diffusion coefficient

Fig. 8). So, there are features like this increased capacity or the improved diffusion of lithium [Li+ diffusion coefficients were foimd to be one order of magnitude higher in the nanocomposites than in pristine V2O5 (50)] that make the performance of the nanocomposite materials superior to the sum of its components... 

The maximum moisture content (M i) and the diffusion coefficient (D) were determined for each material and immersion temperature by fitting the data to Eq. 1. For the higher temperatures, the first plateau was taken to correspond to M . Excellent agreement with theory was observed, as shown by the solid tines in Fig. 1. Thus up to the first plateau the moisture diffusion can be considered to be Fickian. The values of D and M obtained are summarized in Table 1. As expected, both increase with temperature, and at a given temperature the nanocomposites have higher values than neat PP. As stated earlier, this is probably due to the hydrophilic nature of the clay and possibly also to a higher void content.
