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.
