New Strategy to Construct Mechanically Strong and Tough Phenolic Networks by Considering the Effect of Curing Reactions and Physical States on the Cross-Linking Density and Cross-Linking Inhomogeneity

Abstract: How to regulate the conflicting effect of cross-linking density and crosslinking inhomogeneity on the mechanical properties of a thermosetting polymer is of great scientific significance and the key to realizing high mechanical strength and toughness. Herein, a new regulation strategy for the inhomogeneous cross-linking networks is proposed from the viewpoint of curing reactions and physical states. Here, a reactive graphene oxide aerogel (GES) was prepared and employed to modify the hierarchical microstructur… Show more

“…At a reaction temperature of 125°C, isothermal rheology experiments were conducted to prove cross‐linking reaction between PEI and sizing agent in Figure 1H. The development of cross‐linking networks in the low‐frequency area has a sensitive impact on the storage modulus (G′) 40 . The time when G′ equals to loss modulus (G″) was reported as gelation time.…”

“…The development of cross-linking networks in the lowfrequency area has a sensitive impact on the storage modulus (G 0 ). 40 The time when G 0 equals to loss modulus (G 00 ) was reported as gelation time. After gelation time, G 0 exceeded G 00 of sizing agents of GF-6 and GF-12, while G 0 of sizing agent of GF-12 is much higher than that of GF-6.…”
