This study presents a novel perspective towards the understanding of polymer crosslinking from individual molecular chains to the role of aggregates. The aggregate states and crosslinking modes are proposed by engineering amino, epoxy and vinyl terminals upon hyperbranched structures. Benefiting spatial molecular configuration and flexible Si-O-C branches, these hyperbranched structures demonstrate exceptional enhancements in both strength and toughness, and among other superior features, striking a delicate balance between dispersion and aggregation, as well as forming robust nano-interfaces. This research emphasizes the significance of aggregate science in comprehending the intricacies of polymer crosslinking and offers valuable theoretical insights for tailoring material properties at a refined molecular level.
