== Abstract ==

Bio-polyamide nanocomposites were prepared using the two most viable techniques from the industrial point of view: the melt intercalation process and in situ polymerization. The effect of the synthesis approach and the amount of nanofibre were evaluated in order to check their influence on morphological, thermal and mechanical properties.
Regardless of the preparation method, all nanocomposites showed good despersion of nanoclay in polyamide matrix and significant improvements in Young modulus, tensile strenght and heat-distortion temperature were achieved. However, the nanocomposites obtained by in situ polymerization presented higher values since the dispersion of the nanoclay occurs during polymerization, when polymer chains are growing and the viscosity of the matrix is still low.

 Las imagenes de TEM para los nanocompuestos con carga final de 10 %, obtenidos mediante diferentes metodologías se muestran en la Figura 1. Se puede apreciar como en ambos casos la nanocarga está homogéneamente distribuida en la matriz polimérica. Sin embargo, también se observa que los nanocompuestos vía ''in situ'' presentan mayor grado de disgregación de las nanofibras con respecto a los nanocompuestos obtenidos mediante extrusión. Esta diferencia se debe al proceso de obtención; en los nanocompuestos por polimerización, la dispersión se lleva a cabo cuando las cadenas poliméricas están en crecimiento y la viscosidad del sistema es baja, mientras que en los nanocompuestos por extrusión la dispersión se realiza cuando las cadenas han alcanzado su máxima extensión y consecuentemente la viscosidad es significativamente más alta [6].
