“…Such possible interactions allowed alignment of this composite-material caused by orientation of nanoparticles in the fibers surface [56]. Analogous effect was not observed when there is no alignment of f-MWCNTs in the fibers [57,58]. In fact, in such studies the values of Young modulus increased.…”

The production of polymeric fibers by the electrospinning technique stands out as being simple, accessible, versatile and with potential use of polymer microfibers in many areas of science and technology. In this article, polymeric microfibers of PBAT/PLA and carbon nanotubes were obtained using a Fractional Factorial Design. The statistical results, the optical microscopy and scanning electron microscopy (SEM) showed that the addition of MWCNT's had an influence in the diameter of the fibers (1.16 ± 0.22 mm), so that its incorporation decreased the value of the diameter, also they were more uniform and homogeneous. Besides, the MWCNT's provided the fibers a better mechanical resistance, probably being inside the fibers, as well as showed in the analysis of wettability by contact angle.

“…The developed composite showed a 19‐fold increase in modulus as compared to that of neat PMMA. [ 7 ] Ezzeddine et al developed intercalated composites of PMMA and MWCNT. MWCNT was surface modified using conjugated polyelectrolytes leading to enhanced direct current (DC) conductivity, thermal, and mechanical properties.…”

Composites of polymethyl methacrylate (PMMA) as matrix and nickel‐coated multi‐walled carbon nanotubes (Ni‐MWCNT) as nanofillers were prepared using a melt mixing process. In order to improve the dispersion of the nanofillers in the PMMA matrix and thus enhance matrix‐filler interactions, Ni‐MWCNT was treated with amino propyl triethoxy‐silane (APTS). The shielding effectiveness (SE) of the composites improved with increasing Ni‐MWCNT content. In addition, the effects of various combinations of fillers like silver, copper, and nickel nanoparticles on SE have been studied. Among these nanoparticles, copper nanoparticles in combination with MWCNT and Ni‐MWCNT showed optimal shielding effectiveness of 55 dB. The volume and surface resistivity of the composites decreased with increase in nanofiller content. The tensile strength values were increased by 51% at 0.8 wt% loading of Ni‐MWCNT as compared to that of composite without filler. The improvement in tensile strength was further analyzed using micromechanical models. Cone calorimeter studies showed 25.3% reduction in the peak heat release rate for the composite loaded with 1.5 wt% of Ni‐MWCNT as compared to that of neat PMMA. The nanocomposites also showed enhanced thermal stability with the formation of char as the filler content increased.
