  • In questo articolo sono descritte le più recenti metodologie di preparazione di ottenimento di nanocompositi a matrice polimerica. Inoltre sono illustrati i risultati preliminari ottenuti su un sistema polimetilmetacrilato (PMMA) caricato con nanoparticelle di carbonato di calcio (CaCO3) . In particolare, presso i nostri laboratori, è stata messa a punto per il sistema in esame, una nuova metodologia di preparazione detta “polimerizzazione in situ”, la quale ha permesso di ottenere nanocompositi in cui le nanocariche sono disperse in maniera uniforme ed omogenea nella matrice polimerica come dimostrato dall’analisi al microscopio elettronico a scansione (SEM). Tale risultato ha di conseguenza migliorato in maniera elevata le proprietà termiche e meccaniche dei materiali ottenuti in confronto con l’omopolimero. Questo lavoro è stato una prima base delle ricerche sui nanomateriali sviluppati successivamente presso l’ICTP-CNR che ha poi prodotto un brevetto e varie pubblicazioni. C’è infine da sottolineare che questa ricerca è un prodotto della partecipazione dell’Istituto ai seguenti progetti europei: · COST Action 523 · BRITE_EURAM ct: BRPR-CT96-024 (literal)

Abstract
  • Recently, according to the development of the nanotechnique, there is a growing interest in the field of nanocomposites. The employment of inorganic nanoparticle-filled composites can provide high-performance materials that find applications in several industrial fields. In the present work preliminary studies concerning the preparation of polymethylmethacrylate (PMMA)/ CaCO3 nanoparticles composites are reported. The preparation was performed by using in situ polymerization methodology. In particular the nanocomposites have been achieved by a modified radical polymerization of the MMA dispersing the nanoparticles directly into the acrylic monomer. Nanocomposites having the 2, 3, 4 and 6 % by weight of nanoparticles were prepared. The influence of the nanoparticles on the chemico-physical properties of the polymeric matrix and the mode of dispersion were investigated performing thermal, mechanical and morphological analysis.
