Frontal polymerization-triggered simultaneous ring-opening metathesis polymerization and cross metathesis affords anisotropic macroporous dicyclopentadiene cellulose nanocrystal foam

Polymeric solid foams have several beneficial properties such Shampoos as their light weight, thermal insulation or shock absorbance, but it is still challenging to efficiently control the foam architecture.Here, the authors optimize the frontal polymerization of dicyclopentadiene with allyl-functionalized cellulose nanocrystals to rapidly achieve solid foams with Sandwich Makers modified structures and enhanced oxidation resistance.
