“…The mechanical and morphological characterizations were performed on the crosslinked products obtained by mixing the samples with a proper amount of polyamide. Three-point bending flexural tests were performed according to ASTM D790 standard through a dynamometer (Instron 3365, Norwood, MA, USA) at room temperature [ 39 , 40 , 41 ]. Measurements were performed in triplicate on the samples to ensure result repeatability.…”

Coatings have a fundamental role in covering the external surface of yachts by acting both as protective and aesthetic layers. In particular, fillers represent the essential layer from the point of view of mechanical properties and consist of a polymeric matrix, different extenders and additives, and dispersing agents, with the latter having the role to provide good extender-matrix compatibility. In the present work, the effects of dispersing agents with an ionic or steric action on the interactions between hollow glass microspheres and an epoxy-polyamide resin are evaluated. Un-crosslinked filler materials are studied via rheological tests, whereas the mechanical and morphological properties of the crosslinked samples are assessed. The results clearly indicate that steric dispersing agents provide a much greater compatibility effect compared to ionic ones, owing to their steric hindrance capability, thus leading to better-performing filler materials with a less-marked Payne effect, which is here proved to be an efficient tool to provide information concerning the extent of component interactions in nautical fillers. To the best of our knowledge, this work represents the first attempt to deeply understand the role of dispersing agents, which are until now empirically used in the preparation of fillers.

“…Um tipo de argila sintética que vem sendo estudada é a fluoromica Somasif ME-100 por possuir capacidade de inchamento em água [7][8][9]. Somasif ME-100 é o nome comercial de um filossilicato expansível, produzido pela modificação do talco com Na2SiF6, e possui uma estrutura semelhante à montmorilonita (MMT), isto é, em presença solução aquosa se esfolia formando nanocompósitos com matriz polimérica [7][8][9][10][11][12][13][14].…”

“…For instance, MMT is used as filler to prepare rubber/clay composites with good processing, low cost, and lighter weight. Properties of rubber/clay composites, such as mechanical properties, gas barrier properties, and thermal resistance, are markedly improved even at low filling levels . However, due to the high surface activity and electrostatic interaction between two layers, MMT is easily aggregated to exhibit resistance for exfoliation in the rubber matrix .…”

Improvement in mechanical properties of NBR/AO60/MMT composites by surface hydrogen bond

et al. 2020

It is still a challenge to prepare high performance rubber/MMT composites by one‐pot method without solution. In this work, NBR/AO60/montmorillonite (MMT) (NBR/AM) composites were prepared by mechanical blending method and in‐situ formation of surface hydrogen bond was introduced under vulcanization process. Results showed that the polar parts of melting AO60 could partly intercalate into interlayer of MMT and some parts of melting AO60 molecules were absorbed onto surfaces of MMT particles during the vulcanization process. Subsequently, surface hydrogen bonds were constructed among NBR, AO60, and MMT after natural cooling, as evidenced by FTIR, resulting in more complex morphology and good interfacial adhesion in the NBR/AM composite. Consequently, as compared to NBR/montmorillonite (NBR/M) composite, remarkable improvements were found in mechanical properties and energy dissipation at high temperature of NBR/AM composite, which may provide a new prospect for designing high performance damping materials.
