碩士 === 國立臺北科技大學 === 有機高分子研究所 === 93 === Chloroprene rubber (CR)/organic modifier/sodium montmorillonite (NA-MMT) nanocomposites were prepared by melt intercalation. The morphology and thermal properties of the nanocomposites were studied using X-ray diffraction (XRD), transmission electron microscopy (TEM), and thermogravimetric analysis (TGA) and dynamic mechanical analysis (DMA). TEM showed that the silicate layers of clay were dispersed at the nano-scale level in the CR matrix containing less than 10 % of clay. XRD investigation also indicated that the silicate layers of clay were exfoliated, DMA was further performed to investigate the thermomechanical properties of CR–clay nanocomposites containing various amounts of clay. With the increase of organic modifier content, the glass-transition temperature and storage modulus of CR– clay nanocomposites increased .The tensile strength and elongation of the nanocomposites also increased.
