Thermosetting resins (TR) are organic compounds that form rigid solid polymers that under heating, decompose with no plastic state or melting. Such an aspect is useful for their application in refractory systems. Despite their technological importanc

Catalytic graphitization has been used since years, normally by heating from room temperature to 2227 or 3027 °C. Ferrocene was used to induce the graphitization in modified novolak phenolic resins synthesized in laboratory (PR). In this study, the

Graphitization of phenolic resins for carbon-based refractories

Autor: Alessandra de Almeida Lucas, Christos G. Aneziris, Victor C. Pandolfelli, Roberto Bertholdo, C.G. Renda, A.P. Luz

Publikováno v: Ceramics International. 43:8171-8182

The chemical resistance and thermo-mechanical properties of refractories bonded with resole or novolak resins depend on the presence of crystalline carbon phases (preferentially with features close to graphite ones) in their compositions. Although th

A new photocatalyst based on onion-like carbon structures has been designed by heat-treating a modified phenolic resin (PR) modified with ferrocene (Fc). Its photocatalytic activity was investigated by degrading the methylene blue (MB) dye in the pre

Study of phenolic resin and their tendency for carbon graphitization

Autor: C.G. Renda, Roberto Bertholdo

Publikováno v: Journal of Polymer Research. 25

Phenolic resins are important materials in various application sectors due to their outstanding mechanical and thermal properties. However, phenolic resins are known as typical non-graphitized carbon precursor. In this work, important parameters rela
