Resum

En aquest treball, es prediu l'efectiu reforç mecànic de nanocomposites polimèrics que contenen farcits de partícules esfèriques basant-se en un model generalitzat analític de tres fases-sèries-paral·lel, considerant els conceptes de percolació i la regió vítria interfacial. Tot i que el concepte de percolació es pren únicament com una contribució del farcit-xarxa, aquí mostrem que també s'ha de considerar la interfase vítria entre farciment i matriu, que sovint està en l'interval dels nanòmetres, mentre interpretem les propietats mecàniques millorades de nanocomposites polimèrics farcits amb partícules. Per a demostrar la importància de l'equació generalitzada proposada, hem ajustat diversos resultats experimentals que mostren un bon acord amb prediccions teòriques. Així doncs, l'enfocament presentat aquí pot ser valuós per elucidar possibles rutes conceptuals noves per crear nous materials amb aplicacions tecnològiques fonamentals i pot obrir una nova via de recerca per a estudis futurs.

abstract = "In this work, the effective mechanical reinforcement of polymeric nanocomposites containing spherical particle fillers is predicted based on a generalized analytical three-phase-series-parallel model, considering the concepts of percolation and the interfacial glassy region. While the concept of percolation is solely taken as a contribution of the filler-network, we herein show that the glassy interphase between filler and matrix, which is often in the nanometers range, is also to be considered while interpreting enhanced mechanical properties of particulate filled polymeric nanocomposites. To demonstrate the relevance of the proposed generalized equation, we have fitted several experimental results which show a good agreement with theoretical predictions. Thus, the approach presented here can be valuable to elucidate new possible conceptual routes for the creation of new materials with fundamental technological applications and can open a new research avenue for future studies.",
