A fabrication method and application of topological elastomers with highly branched structures, low modulus and high elasticity. The topological elastomers comprise dendritic macromolecules. The fabrication method includes direct crosslinking, post-crosslinking, grafting, and copolymerization. The performance of the elastomer can be easily tuned via changing the topology of the polymer network. The breakthrough of this invention lies in that these topological elastomers with highly branched structures are having low modulus and high elasticity, which would expand its application in the field of elastomer. Notably, the variety of topological elastomers, the versatility of curing chemistries, the availability of a wide variety of monomers, and the various polymerization methods are enabling the fabrication of topological elastomers with feasibility and efficiency.
