Guilhermino José Macêdo Fechine has a degree in Materials Engineering from the Federal University of Paraíba (1996), a master's degree in Chemical Engineering from the Federal University of Paraíba (1998), and a PhD in Chemistry from the Federal University of Pernambuco (2001). Research productivity researcher at CNPq (level B). He is a member of the Board of Directors of ABPol (Brazilian Polymer Association) and serves as its Director of Innovation and Technology. In 2025, he was the chairman of the 18th Brazilian Polymer Congress, held in Campos do Jordão from October 19th to 23rd. He has two postdoctoral internships at USP: one at the Chemistry Institute (2002 to 2005) in hydrogels, and the other at the Polytechnic School (2005 to 2007) in blends and composites based on biodegradable polymers. Visiting professor at the National University of Singapore - NUS throughout 2013, working in graphene transfer processes. He was a visiting researcher for a period of 1 month at Case Western Reserve University (Ohio, USA) in 2016, the Bulgarian Academy of Science (Sofia, Bulgaria) in 2018, and the Institute for Composite and Biomedical Materials IMCB (Portici, Italy) in 2019. Since 2008, he has been an undergraduate and postgraduate professor at Mackenzie Presbyterian University. He is a researcher at the Mackenzie Institute for Research in Graphene and Nanotechnology (MackGraphe). The current topics covered in their research include understanding the interactions between polymers (including biodegradable ones) and various 2D materials (graphene, MoS2, hBN, phosphorene, etc.), whether for developing new mixing strategies or for obtaining and characterizing polymer nanocomposites for different applications.

Biodegradable polymers such as poly(hydroxybutyrate-co-hydroxyvalerate) (PHBV) are presented as a possible alternative to the environmental disadvantages associated with petroleum-derived polymers. However, the mechanical properties of PHBV fall short of what is desired for technological applications. The addition of graphene and derivatives as well as nanocellulose crystals have the pote…

Thermal management is a vital feature for safety, reliability, and performance of several applications such as electronic assembly and packaging, solar energy and medical devices, automobile and aerospace structures, etc. Incorporating high contents of thermally conductive fillers has been the most efficient and economical strategy to improve the thermal conductivity (TC) of polymer matri…
The rheological behavior of polymer nanocomposites has attracted considerable attention because most industrial processing and molding techniques involve the flow of the material in the molten state. It is well established that rheometry is a powerful tool to investigate nanocomposite microstructures, and several studies have been carried out with the aim to identify changes in the viscoe…
This project has the main objective of developing a route of insertion of graphene oxide (GO) in polymeric matrixes in order to obtain a good dispersion and maintain the structural integrity of the nanoparticle. Two polymeric matrices will be used: polypropylene (PP) and poly (ethylene terephthalate) (PET). Are being sought, especially, improvements in the mechanical and barrier propertie…
