MDSC, by varying the furnace temperature sinusoidally, has been used to determine the specific heat of PA6 materials (similar measurements have been performed for polypropylene nanocomposites). The materials were heated from -80°C to 250°C at 2°C/min. The reversible signal recorded during the experiment is related to the specific heat of the sample. The specific heat values versus temperature for the different PA6-based formulations are given in Figure 19.3, showing no significant differences between different formulations. The peaks noted on the specific heat curves correspond to the transition from the solid to the liquid states.

Polypropylene nanocomposites are remarkable for their better mechanical properties, such as high tensile strength and modulus, and for their dimensional stability. They have a wide range of applications in the automotive sector [7-11]. The PP composites are used in automotive industry as battery supports, instmment panel carriers, body panel reinforcements, front-end modulus, underbody aerodynamic covers, electronic boxes, pedals and their supports, door panels and door modules, bumper beams, fender extensions, wheel covers, hub caps, and trim rings for wheels (Fig. 11.4).

Layered siUcate/polypropylene nanocomposites were prepared by melt intercalation method. Homopolymers PP alone and maleic anhydride-grafted polypropylene (PPgMA) as a compatibiUzer were used as the matrix. Clay (Na montmorillonite, MMT) particles were used to obtain silicate nano-layers within the PP matrix. Structural modification of MMT... 

The production of polypropylene nanocomposites is shown in Figure 9.The homopolymer PP was fed into Haake two-roll mixer at 190 o C. After melting of the PP in 1 min, clay particles in the amounts of 3, 5 and 10 wt. % were added into molten PP and the mixing was continued for 10 min in the mixer. The blended samples were collected and left for cooling. After cooling, the blends were pressed into 100 mm x 100 mm samples having a...
