“…These reasons could have contributed to lower than expected elastic modulus of the composites in spite of excellent MWCNT dispersion in the matrix (as observed from Figures 2 and 3). Similar observations have been reported earlier in [42][43][44]. The tensile strength of the composites as observed in Figure 9 happens to be almost identical to the stress at yield and the stress at break.…”

“…Several processing methodologies such as solution casting [59][60][61], melt mixing [62][63][64][65][66][67], solution mixing [59,60,68], different methods of in situ polymerization of the monomer in the presence of CNTs [69,70], coagulation spinning [71], mechano-chemical pulverization [72], solid-state shear pulverization [73], electro spinning [74] etc. have been adopted for the synthesis of polymer-MWCNT composites.…”

“…As the interfacial energy difference between polar thermoplastics like polycarbonate (PC), polyvinyl chloride (PVC) etc. with the hydrophilic CNTs is significantly low, excellent CNT dispersion is achievable with these matrices resulting in extremely low filler percolation thresholds for the final macroscopic properties [67,[76][77][78]. On the other hand polyolefins exhibit a very high interfacial energy difference with the CNT limiting the level of CNT dispersion in the composite [62,79].…”

“…La facilidad de dispersión de los nanotubos en la matriz depende en gran medida de la naturaleza química del polímero. Algunos polímeros como el policarbonato (PC) 102 , el polivinil alcohol (PVOH) 103 y la poliamida (PA) 104 han demostrado su mayor facilidad para obtener una buena dispersión de los NTC. Por el contrario, las poliolefinas son consideradas las matrices menos afines a los NTC debido a su carácter apolar, y por lo tanto, la obtención de una buena dispersión es mucho más complicada.…”
