Embodiment 1

[0118] Process for preparing nanocomposite polymer blends comprising PC, PP and MWCNT

Embodiment 1a

[0120] In the Brabender mixer, the temperature was set to about 230°C. After reaching the desired temperature, polycarbonate (PC) was added to the mixer at a concentration of about 49.75 (w / w%). Once the PC is melted, polypropylene (PP) is added at a concentration of about 49.75 (w / w%). The blend of PC and PP was then mixed at about 60 rpm for about 2 minutes. Thereafter, MWCNTs were incorporated into the blend system at a concentration of about 0.5 (w / w%). The blend was mixed again for about 8 minutes at about 60 rpm. The resulting blend is then subjected to a temperature of about 230°C and about 100 kg / cm 2 Compression molding under pressure for about 1 minute. Thereafter, the blend was cooled to room temperature under the same pressure to obtain a nanocomposite polymer blend comprising PC, PP and MWCNT.

Embodiment 1b

[0122] In the Brabender mixer, the temperature was set to about 230°C. After reaching the desired temperature, polycarbonate (PC) was added to the mixer at a concentration of about 57.5 (w / w%). Once the PC is melted, polypropylene (PP) is added at a concentration of about 37.5 (w / w%). The blend of PC and PP was then mixed at about 60 rpm for about 2 minutes. Thereafter, MWCNTs were incorporated into the blend system at a concentration of about 5 (w / w%). The blend was mixed again for about 8 minutes at about 60 rpm. The resulting blend is then subjected to a temperature of about 230°C and about 100 kg / cm 2 Compression molding under pressure for about 1 minute. Thereafter, the blend was cooled to room temperature under the same pressure to obtain a nanocomposite polymer blend comprising PC, PP and MWCNT.

Abstract

The present disclosure relates to polymer nanocomposite blends comprising polycarbonate (PC), polypropylene (PP) and multi-walled carbon nanotube (MWCNT). The present disclosure further relates to a method of preparing the polymer blend nanocomposite comprising polycarbonate (PC), polypropylene (PP) and multi-walled carbon nanotube (MWCNT). In particular, the MWCNTs stitch the co- continuous interface of PP / PC blends by the selective localization at the interface of the PC / PP blends to give rise to a double percolating network structure having a stable and homogenous morphology with excellent mechanical properties and high performance.

Description

technical field [0001] This disclosure relates to the field of polymer science. More specifically, the present disclosure relates to polymer blend nanocomposites comprising polycarbonate (PC), polypropylene (PP), and multi-walled carbon nanotubes (MWCNT). The present disclosure also relates to methods of preparing polymer blend nanocomposites comprising PC, PP and MWCNTs and applications of said nanocomposites. Background technique [0002] Polypropylene (PP) and polycarbonate (PC) are thermoplastics with good mechanical properties and processability. The low heat resistance and poor low-temperature impact properties of PP limit its application in high-performance fields. To overcome this disadvantage, blending of PP with thermoplastics with higher heat resistance and high impact properties is practiced. [0003] Polycarbonate (PC) is an expensive engineering thermoplastic with high heat resistance and high impact properties, so the blending of PP with PC can provide new ...
