摘要：

Composites of poly(furfuryl alcohol) grafted onto silica, with different percentage of grafting, have been investigated by scanning electron microscopy, elemental analysis and UV/Vis-reflectance spectroscopy. The size of the silica particles used for the coating procedure is not changed till a percentage of grafting to around 30%. A content of polymer higher than 35 wt.-% enhances the bonding between the particles due to the crosslinking of poly(furfuryl alcohol) on the surface with those in solution leading to the agglomeration of the particles. A general model of cross-linked poly(furfuryl alcohol)-silica composites is suggested.
