Nanotechnology as a New Approach for Material Recycling of PET Bottles

With a view to reduce the mentioned degradation and to increase delamination in the system, the selected commercial organoclays were additionally modified. The principle of the treatment consists in silanization of clay hydroxy groups by the selected silane in aqueous-methanolic environment. The bonded functional groups can facilitate chemical or physical interaction of the filler with the polymer matrix and eliminate the hydrolysis of PET by the silicate hydroxyl groups. In this presentation, recycled PET-clay nanocomposites using commercial as well as modified organoclays are analysed by rotational rheometry and the effects of silicate modification on the melt flow properties are discussed.
