Santa Catarina State University, UDESC, CCT, Joinville, Brazil
Sérgio Pezzin is Full Professor at the State University of Santa Catarina (UDESC), Department of Chemistry, in Joinville, Brazil. He was Coordinator of the Graduate Program in Materials Science and Engineering, Head of Department, Coordinator of the Undergraduate Course in Chemistry and Director of Research and Graduate Studies at the Center for Technological Sciences.
Prof Pezzin works mainly in nanocomposites, self-healing materials, and biodegradable polymers, having supervised more than 40 Master’s/PhD students.
He was a Visiting Professor/Researcher at the Polytechnic University of Valencia (Spain), the GKSS -Helmholz Center (Geestacht, Germany), the Technical University Hamburg-Harburg and the Karlsruhe Institute of Technology (Germany).
Prof. Pezzin was also Director of the Southern Regional of the Brazilian Polymer Association (ABPol-Sul) and Chair of the XVII Brazilian Polymer Conference (CBPol).
The advancement of electrospinning technology observed in recent decades, combined with its versatility and relatively low cost, favored the expansion of the use of electrospun membranes for a wide variety of applications, such as air/water filtration systems[1], tissue engineering[2,3] and sensors[4]. Here we will present the latest developments on electrospun materials and devices for electrospinning at the Grupol-UDESC and DBM Eletrotech. For instance, the development of nanostructured PVC/CNT membranes with adjustable hydrophobicity and high porosity for humidity sensors[4], in situ sol-gel PVC/silica nanofibers – with the development of a siloxane interpenetrating network during electrospinning, and coaxial electrospinning of core-shell structures (‘nanocables’). ‘Green electrospinning’ processes will also be highlighted, with the development of PVA membranes from aqueous solutions containing bioactive ingredients (cosmeceuticals) for direct application on skin by a portable electrospinning device[5], and the production of cellulose-based electrospun fibers.
