“…The minimum torque ( M L ), maximum torque ( M H ), and optimum curing time ( t 90 ) of the blends are related to the formation of crosslinked structure. Larger t 90 is expected for FSi especially at a high loading level due to the acidity of FSi . It is found in Table that M L , M H , and t 90 increase with the increase of the silica content for the same filler, and are in the sequence of FSi > PSi > MPSi at the same loading.…”

“…As a result, silicone rubbers provide excellent utility in sealing, gas, and aerospace industry . Silicone elastomers are also well accepted in other applications such as microfluidics, cell culture substrates, flexible electronics, and medical devices because of their biocompatibility, optical transparency, moldability with submicron resolution, and high oxygen permeability . However, vulcanized neat silicone rubbers exhibit poor mechanical properties because of their low T g and very weak intermolecular interactions.…”

In this study, high‐temperature vulcanized silicone rubbers (HTV‐SRs) using fumed silica (FSi), precipitated silica (PSi), and modified precipitated silica (MPSi) as reinforcing fillers were prepared. The effect of morphology and surface chemistry of the silica on the thermal and mechanical properties of the resultant silicone rubbers was investigated using curing rheometer, scanning electron microscopy, mechanical test, and dynamic mechanical analysis. The thermo‐oxidative stability and solvent resistance of the vulcanized silicone rubbers were further evaluated via heat ageing test, extraction, and swelling experiments. It is shown that the mechanical properties (tensile modulus and tensile strength) of the as‐prepared HTV‐SRs are in the order of FSi > PSi > MPSi, which could be attributed to the molecular interaction between the filler and the matrix. FSi has the highest surface area, which enhances the hydrogen bonding interaction between the filler and the silicone matrix; while MPSi, in which part of SiOH groups have been consumed during modification, shows the weakest interaction among the three. The filler–matrix interaction could also explain the lowest swelling and sol fraction in FSi‐filled HTV‐SR, and the low viscosity and good processibility of PSi‐ and MPSi‐filled HTV‐SR. Furthermore, it is also shown that the MPSi‐filled HTV‐SR exhibits the highest retention of mechanical properties after thermal aging at 250 °C for 24 h, which could be attributed to the lowest acidity of the fillers. The possible mechanism for acid catalyzed hydrolytic chain scission and intramolecular chain backbiting has been proposed. © 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 135, 46646.

“…Therefore, it is necessary to develop surfaces with quantifiable physical structures for optimization of anti-biofouling action. We previously reported a simple and mold-free technique for fabricating surfaces by 3D printing ( He et al, 2017 ), which may assist in the precise design and manufacture of physical surfaces to combat biofouling ( Mazinani et al, 2019 ).…”

The use of anti-biofouling polymers has widespread potential for counteracting marine, medical, and industrial biofouling. The anti-biofouling action is usually related to the degree of surface wettability. This review is focusing on anti-biofouling polymers with special surface wettability, and it will provide a new perspective to promote the development of anti-biofouling polymers for biomedical applications. Firstly, current anti-biofouling strategies are discussed followed by a comprehensive review of anti-biofouling polymers with specific types of surface wettability, including superhydrophilicity, hydrophilicity, and hydrophobicity. We then summarize the applications of anti-biofouling polymers with specific surface wettability in typical biomedical fields both in vivo and in vitro, such as cardiology, ophthalmology, and nephrology. Finally, the challenges and directions of the development of anti-biofouling polymers with special surface wettability are discussed. It is helpful for future researchers to choose suitable anti-biofouling polymers with special surface wettability for specific biomedical applications.

Thus, silicone rubber finds use in high-tech applications, such as sealing, gas and aerospace industry, microfluidics, flexible electronics, medical devices, and electrical insulators, among others [2,3,4,5,6]. However, silicone rubbers usually require the use of fillers to improve their mechanical strength and stiffness.…”

Multifunctional Silicone Rubber Nanocomposites by Controlling the Structure and Morphology of Graphene Material

et al. 2019

View full text Add to dashboard Cite

Multifunctional elastomer nanocomposites have been applied in several high-tech fields. The design of materials with tailored properties capable of tuning their performance is a topical challenge. Here, we demonstrate that it is possible to modulate the mechanical and transport properties of silicone rubber nanocomposites by controlling the structure, chemical composition and morphology of the graphene material. Intrinsic graphene properties, such as remaining oxygen groups, specific surface area, and aspect ratio, among others, have a profound effect on the final properties of the nanocomposite. Thus, the thermal conductivity benefits from larger filler size and high aromatic restoration. Whereas mechanical properties and electrical conductivity require a proper balance between filler/polymer matrix interaction and a partial aromatic restoration.
