Hybrid materials based on rubber blend nanocomposites

Abstract

In this applicative work, two types of silica filler were used to increase the adhesion strength between steel and elastomeric hybrid materials based on chlorosulfonated polyethylene rubber (CSM) and polychloroprene rubber (CR) as network precursors. Precipitated silica (PS) with the average size of primary particles 15 nm and diatomaceous earth (DE) with the average size of primary particles 28 μm were used to ascertain differences in metal‐elastomer compounds adhesion strength caused by different particle size. The ratio of network precursors in CSM/CR rubber blends was 50:50 (w/w). The filler loading was in the range of 0–35 phr. Characteristics of the obtained composites were examined by combining the cure kinetics, adhesion strength and the dynamic mechanical properties. The viscoelasticity of obtained hybrid materials was assessed by the mechanical spectrometer (in a single cantilever bending mode) in the temperature range from −50 °C to 150 °C using multifrequency mode.

Development of hydroxyapatite nanoparticles reinforced chlorinated acrylonitrile butadiene rubber/chlorinated ethylene propylene diene monomer rubber blends

“…Dick and Santos reported the preparation of HA incorporated natural rubber (NR) by a solution mixing method, 18 but the mechanical strength of NR is not much improved due to the poor interaction between polar HA and non‐polar NR. The production of nanocomposites based on rubber blends has greatly increased due to their well‐balanced physical and mechanical properties, easy processability, and relatively low production cost 19 . Homogeneity of mixing and retention of the compatibility during the mixing and vulcanization are the most relevant issues for the preparation of rubber blend nanocomposites.…”

Fabrication of High-Performance Natural Rubber Composites with Enhanced Filler–Rubber Interactions by Stearic Acid-Modified Diatomaceous Earth and Carbon Nanotubes for Mechanical and Energy Harvesting Applications

“…However, owing to the larger particle size and polarity, it remains challenging to improve the tensile properties other than the stiffness of rubber composites. Although there are many possibilities for enhancing the properties of rubber composites with pure or modified diatomaceous earth, only a few reports have been published [41][42][43][44][45]49]. To the best of our knowledge, this is the first study on diatomaceous earth and carbon nanotubes as hybrid reinforcing fillers in natural rubber composites for suitable applications in mechanical and self-powered electromechanical sensing.…”

“…However, despite possessing several advantageous properties for use as a filler in rubber compounding, diatomaceous earth has drawbacks associated with polar functional groups on its surface. Because diatomaceous earth is a naturally abundant, cheap material with a highly porous structure, it is used as a filler in different rubber composites [41][42][43][44][45].…”

Modified ethylene/α‐octene co‐polymer elastomer composites with sacrificial bonds crosslinking networks and their reinforced mechanical performance

“…Physical modification is a common method because of its convenient modification process. [ 8 ] Blending of different polymers directly was carried out to prepare composites to endow them with other properties required in application. [ 9–13 ] In addition, the strength of POE could be significantly improved by filling filler in POE matrix, such as crushed straw, graphene oxide modified by octadecyl (ODA‐GO), and enzymatic hydrolysis lignin.…”
