Synthetic lamellar nanofillers alpha-ZrP based elastomeric nanocomposites : influence of the fillers modification on the mechanical and gas barrier properties
type: Dataset
description: This work concerns the study of the modification of synthetic lamellar nanofillers (α-ZrP) and their influence on mechanical and gas barrier properties of elastomeric nanocomposites (SBR). This study is part of improving the tire tightness. One of the originalities of this work is the introduction of hydrophilic nanofillers through an aqueous dispersion (slurry) in the hydrophobic SBR matrix. The first step of this work was to undertake several types of nanofiller modifications state in order to study their intercalation/exfoliation mechanisms in a slurry. These different families of modified fillers were then used to make nanocomposites with different ways of implementations: mainly solvent and latex ones. The influence of, (i) the nature of the intercalating agent, (ii) the initial nanofiller interlayer distance and (iii) the nanocomposite implementation processes, on the morphology and final properties of materials were studied. The synergy of these three parameters was demonstrated and the importance of controlling the modified filler/matrix interactions on the gas transport and mechanical properties was also proved. Among all the synthesized materials, a formulation was put forward which allowed to achieve interesting mechanical and barrier properties. This formulation, processed by the latex route, is based on the use of aminosilane modified nanofillers and the Si69 coupling agent
