Organic-inorganic interpenetrating polymer networks and hybrid polymer materials prepared by frontal polymerization

Abstract

Novel polyacrylamide‐based hydrogels containing 3‐(trimethoxysilyl)propyl methacrylate and/or tetraethoxy silane were synthesized by means of frontal polymerization, using ammonium persulfate as initiator, N,N′‐methylene bisacrylamide as crosslinking agent and dimethyl sulfoxide as solvent. The obtained samples were treated at pH of 2 or 5 to induce the sol–gel reaction and evaluate their swelling behavior in the conditions. The occurrence of this reaction was assessed by solid‐state NMR. Moreover, the thermal properties of the dry materials were studied by differential scanning calorimetry and thermal gravimetric analysis, and their water‐contact angles were measured. It was found that the amount of Si affects the extent of swelling and the hydrophilicity of the resulting materials. © 2013 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym.

Effect of limonene on the frontal ring opening metathesis polymerization of dicyclopentadiene

“…Frontal polymerization (FP) is a synthetic technique that allows the conversion of monomer into polymer by formation and consequent propagation of a hot polymerization front, able to self‐sustain and propagate throughout the monomeric mixture. This technique allows obtaining polymer materials by a simple reaction route, short time, and low energy consumption …”

Advances in the frontal ring opening metathesis polymerization of dicyclopentadiene

“…FP allows the fast conversion of monomer into polymer by exploiting the heat produced by the exothermicity of the selfsame polymerization reaction. An igniting event causes the formation of a hot polymerization front that allows the propagation of the reaction: the front is able to self‐sustain and propagate throughout the monomeric mixture …”

Preparation and interaction study between fullerene and graphene in a polymeric matrix

“…It is well known that a wide (UV and visible) absorption range is desirable for organic photovoltaics [20,[27][28][29][30][31][32][33]. Frontal Polymerization (FP) is a polymerization technique that allows the conversion of a monomer into a polymer by formation and consequent propagation of a localized reaction zone [7,8,11,[34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51][52]. The resulting polymerization front is able to self-sustain and propagate along the whole reactor.…”
