On the design and properties of scaffolds based on vertically aligned carbon nanotubes transferred onto electrospun poly (lactic acid) fibers

Autor: Claudia A. Razzino, Fernanda Roberta Marciano, Anderson Oliveira Lobo, Francílio de Carvalho Oliveira, Bruno V.M. Rodrigues

Publikováno v: Materials & Design, Vol 127, Iss, Pp 183-192 (2017)

Herein, we propose the design of a nanoscaffold based on the hot-press transfer of vertically aligned multi-walled carbon nanotubes (VAMWCNT) onto matrices of electrospun poly (lactic acid) (PLA) fibers. To this end, we created a three-dimensional, b
