Bonding of rubber and poly carbonate waste

The processing of rPC/CR mixtures is done with an internal mixer (Brabender 50EHT with counter-rotating blades) after drying of the polymers at 90°C for 24 hours. Then, the combination of the CR and the PC is done at 240°C for 10 minutes at 40 rpm.The molten mixture is then pressed at 240°C, with 5 MPa of pressure, for 5 minutes to obtain plates measuring around 4 x 250 x 250 mm, which 

The traction tests are performed on an MTS Syneigie RTIOOO machine, with samples conforming to the IS0527 standard, and a rate of traversing of 1 nuamin. The experimental points correspond to an average valne ealcnlated on the basis of five samples. 

apart from satisfactory mechanical properties, a mixture of recycled polymers such as that which we have just examined (rPC/CR) can also exhibit interesting electrical properties, we will have succeeded in creating a multifunctional material simply from waste polymers. This can then be considered an upgrading of the material, because in this case it would be possible to target higher-level apphcations than those initially intended for the virgin materials. 

Smart materials [FEL 11] such as conductive polymer composites (CPCs) could potentially offer such capabilities, and we shall now examine the capacities of rPC/CR mixtures in this domain in greater detail. 

In order to render a plastic conductive although it is, by nature, an electrical and thermal insulator (with the exception of intrinsically conducting polymers, ICPs), we need to dope it with electrically conductive fillers such as steel microfibers (pFSs) [FEL 06], CNPs [FEL 01] or indeed carbon nanotubes [FEL 11]. By gradually varying the proportion of fillers in the polymer matrix, we see that its resistance goes
