Frontal polymerization as a convenient technique for the consolidation of tuff

Abstract

Abstract:Frontal Polymerization was successfully exploited as an innovative technique for the consolidation of Neapolitan Yellow Tuff, the main volcaniclastic rock of Campania region (Italy). The protocol used and the full characterization in terms of mechanical properties of the resulting consolidated stone are presented here and discussed together with the data obtained by X-ray tomography as a non destructive analytical technique for determining the internal map of the consolidated material. The proposed treatment definitely succeeded from the technical point of view resulting in an enhancement of mechanical properties.

Frontal Polymerization

“…The Hilti patents propose FP as a means to rapidly cure a chemical anchor. Vicini et al developed an FP method for the consolidation of stone [74,75]. We have focused on cure-on-demand polymerization.…”

A clustered ground‐glass hepatocyte pattern represents a new prognostic marker for the recurrence of hepatocellular carcinoma after surgery

“…Since then, a considerable amount of research in this field has been developed. Our group used FP to synthesize hydrogels,6–9 polymer‐based nanocomposites,10 unsaturated polyester/styrene resins,11, 12 nanocomposites containing polyhedral oligomeric silsesquioxanes,13 interpenetrating polymer networks,14 diurethane acrylates,15 for the consolidation of tuff,16 and to obtain polyurethanes 17, 18. In our most recent articles, we used FP to copolymerize successfully an azo monomer with an acrylic monomer,19 to obtain stimuli‐responsive hydrogels containing partially exfoliated graphite,20 and to synthesize thermoresponsive super water absorbent hydrogels,21 hybrid inorganic/organic epoxy resins 22…”

Preparation and optical characterization of two photoactive poly(bisphenol a ethoxylate diacrylate) copolymers containing designed amino‐nitro‐substituted azobenzene units, obtained via classical and frontal polymerization, using novel ionic liquids as initiators

“…FP was discovered in Russia by Chechilo and Enikolopyan in the 1970s,27 and their work was pushed further in 1984 28. Our group has used this technique for the consolidation of porous materials,29, 30 to synthesize interpenetrating polymer networks,31 unsaturated polyester/styrene resins,32, 33 hydrogels,34–37 polymer‐based nanocomposites,38 and polyhedral oligomeric silsesquioxanes 39. In our most recent articles, we used FP to synthesize hybrid inorganic/organic epoxy resins,40 to obtain stimuli‐responsive hydrogels containing partially exfoliated graphite,41 and to copolymerize successfully an azomonomer into two different polymer matrices 42, 43.…”
