Clay was organically modified with one kind of ionic liquild. Organical clay obtained was used to prepare poly(propylene) (PP)/clay nanocomposites by solution blending. Flourier transform infrared (FTIR), wide-angle X-ray diffraction (XRD) and thermogravimetric analysis (TGA) revealed that the ionic liquild was loaded in the galleries of organically modified clay. TGA result show the thermal stability of organically modified clay was superior to clay. XRD patterns indicated that the d-spacing of clay layers increased to 2.96 nm from 1.22 nm of clay. XRD patterns of PP/clay nanocomposites show that clay layers were dispersed in PP matrix by nanometer size.

Thermal Stability Of

A series of polyimide (PI)-organically modified clay nanocomposites were made to enhance tensile modulus, thermal stability of PI. PI was made from 3, 3', 4, 4'-biphenyl tetracarboxylic dianhydride (BPDA), p-phenylediamine (PDA).  Montmorillonite (MMT), one type of layered clay, was treated by dodecylamine salt.  XRD indicated that organically modified montmorillonite (OMMT) layers were exfoliated and dispersed into PI-film.  Tensile measurements indicated that small amount of OMMT (up to 3%) increased tensile modulus nicely.  The glass transition temperatures (Tg) of the nano-composites are higher than those of pristine PI.  Thermal gravimetric analysis (TGA) showed that nanocomposites have higher decomposition temperatures in comparison with the original PI.  Keywords: Polyimide; Organically modified clay; Nanocomposites; Dodecylamine. © 2009 JSR Publications.

Spherulite Morphology

Poly(trimethylene terephthalate) (PTT), and three different rubbers(maleated styrene-butylene-co-ethylene-styrene copolymer (SEBS-g-MA), ethylene-propylene-diene copolymer grafted with maleic anhydride (EPDM-g-MA) and maleic anhydride grafted poly (ethylene-octene) (POE-g-MA)) were mixed in the melt state. Their rheological properties and spherulite morphology were investigated. Rheological properties shows torque decreases with the time increasing for all blends. PTT/SEBS-g-MA blend have better processability than PTT/EPDM-g-MA and PTT/ POE-g-MA blend. Polarizing optical microscopy (POM) experiments showed that the introduction of rubber chain greatly affects the size of the PTT spherulites. Small-sized PTT spherulites were formed when rubber added to PTT.
