Mesoporous silica reinforced polybutadiene rubber hybrid composite

Abstract

Polybutadiene rubber (BR) hybrid composites reinforced with mesoporous silica (MPS)/nanoclays, silica and MPS/carbon black were prepared. The primary focus of this research was to incorporate the mesoporous silicate (MPS), e.g., mobil composition of matter (MCM-41) as reinforcing filler in the BR matrix. The textural properties of the mesoporous materials were characterized by powder X-ray diffraction (XRD), transmission electron microscopy and N 2 isothermal adsorption measurements. The quantity of MCM-41 in the BR matrix was first optimized and the similar optimized quantity of different MPS was compared in terms of tensile strength. The composites were characterized by XRD and scanning electron microscopy. The composite containing 10 phr-loaded MCM-41 showed 250 % improvement in tensile strength compared to the matrix devoid of nanomaterial. The effects of co-incorporation of two different kinds of nanomaterials having different nanostructures, e.g., layered montmorillonite and particulate MCM-41 were also studied. MCM-41 enhanced the mechanical strength of BR almost double the value compared to precipitated silica at the same filler loading. The morphological features of the composites were well corroborated with the mechanical properties.

Influence of synthesized nano-ZnO on cure and physico-mechanical properties of SBR/BR blends

“…This may be due to some synergistic effect between nanofiller, sepiolite and conventional filler, carbon black [31]. The similar kind of effect has also been studied in our previous study using mesoporous silica as reinforcing filler in the poly butadiene rubber matrix in the presence of nanoclays, silica and carbon black [32].…”

Mesoporous Materials: From Synthesis to Applications

“…The high porosity of the mesoporous silica allows them to host a high amount of polymer chains. Accordingly, several composites have been reported such as poly(ethylene oxide)/MCM-41, styrene butadiene rubber/MCM-41 [21]. Generally, the obtained composites present a higher elastic modulus at every evaluated temperature indicating higher polymer chain stiffness.…”

A review on new mesostructured composite materials: Part II. Characterization and properties of polymer–mesoporous silica nanocomposite

“…The large variety of polymer systems used in nanocomposites preparation with mesoporous silica can be divided into four categories. (i) vinyl polymers, for example, methyl methacrylate, 13–16 other acrylates, 17 polystyrene 18–20 , and poly vinyl acetate (PVAc); 21 (ii) condensation (step) polymers like epoxy polymer resins (EPR), 22–26 nylon 6 (N6), 27 N66, 28 polyethylene oxide (PEO), 29,30 polybutadiene, 31 butadiene copolymers, 32,33 natural rubber, 34 silicone rubber, 35 phenolic resins, 36 polyimides, 37 and polysulfone; 38 (iii) polyolefins including polypropylene (PP) 39–43 and polyethylene (PE); 44,45 and (v) specialty polymers such as polypyrrole (PPY) 46 and polyaromatics such as polyaniline (PANI). 47…”
