WebMar 18, 2015 · PF resin (with the phenol/formaldehyde molar ratio of 1:2.2) was synthesized by batch polymerization. Firstly, the mixture of phenol and one-third of the formaldehyde and NaOH was put into a three-necked round-bottom flask, then heated to 85 °C, and kept for 1 h. WebUnder this subsection, the effect of addition of CNT and carbon fibers on the initial stage of pyrolysis is discussed. 3.2.1. CNT-Phenolic resin composite. Pyrolysis simulations are …
