Use of experimental design to obtain polymeric microfibers with carbon nanotubes

Abstract

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.

“…Moreover, DoE helps to choose the best combination of them for optimizing the selected P.F., or at least to contain its deviation in response to the action of uncontrollable factors (robust design, RD) [38]. An approach based on DoE was successfully adopted to produce polymer mi bers with carbon nanotubes through electrospinning experiments [39], and has rec been combined with artificial intelligence (AI) to develop the sustainable electroche synthesis of zeolitic imidazolate frameworks (ZIF-8) [40].…”

“…By following the aforementioned methodological steps, DoE on the basis of 2 points D*⊂ D generates scattered data for the P.F., which is required for carryin sensitivity analysis by means of Dex Scatter Plot (DSP), Main Factor Plot (MFP) an An approach based on DoE was successfully adopted to produce polymer microfibers with carbon nanotubes through electrospinning experiments [39], and has recently been combined with artificial intelligence (AI) to develop the sustainable electrochemical synthesis of zeolitic imidazolate frameworks (ZIF-8) [40].…”
