The surface of your 120 Mu sample presents little grains/platelets of material within a stepped layer construction, even though regions of increased adhesive conversation are mostly with the interface amongst grains. The 120 Mdv sample appears to comprise more substantial flatter platelets compar

The area roughness for your 120 Mdv sample is far bigger than other devulcanized samples, and it truly is revealed in Fig. 6. The rubber particle provides a really rough surface area, and there are signs of stretched rubber in the course of the particle. ??????????????????????????????????????????

Outcomes confirmed that as being the particle dimensions decreases, the efficiency from the devulcanization raises. The reduction of the particle sizing makes it possible for the solvent molecules to penetrate the polymer network more effortlessly and much more floor region is offered. More compact
