“…To improve the stabilities of PDMS, many kinds of nano materials, such as carbon nanotubes (CNTs) [13][14][15], silica nanoparticles [16][17][18], and graphene [19] have been doped into PDMS. Wu et al reported that the elastic modulus of PDMS was increased to 2.34 MPa by adding carbon nanotubes [13].…”

Abstract:The effects of silica nanoparticles on the properties of a commonly used Sylgard 184 polydimethylsiloxane (PDMS) in microfluidics were systemically studied. Two kinds of silica nanoparticles, A380 fumed silica nanoparticles and MCM-41 mesoporous silica nanoparticles, were individually doped into PDMS, and the properties of PDMS with these two different silica nanoparticles were separately tested and compared. The thermal and mechanical stabilities of PDMS were significantly enhanced, and the swelling characteristics were also improved by doping these two kinds of nanoparticles. However, the transparency of PDMS was decreased due to the light scattering by nanoparticles. By contrast, PDMS/MCM-41 nanocomposites showed a lower coefficient of thermal expansion (CTE) owing to the mesoporous structure of MCM-41 nanoparticles, while PDMS/A380 nanocomposites showed a larger elastic modulus and better transparency due to the smaller size of A380 nanoparticles. In addition, A380 and MCM-41 nanoparticles had the similar effects on the swelling characteristics of PDMS. The swelling ratio of PDMS in toluene was decreased to 0.68 when the concentration of nanoparticles was 10 wt %.

“…After silane functionalization, both conditions were improved by the attachment of silane molecules onto CNTs surface. Vast et al, 2009, used two types of silane: 7-OTS and n-OTCS, which differ only by the nature of their end groups. These were used in order to compare dispersion of purified and silanized MWNTs in a thermally curable silicone rubber: Sylgard®184 and the effect on the Young's modulus.…”

“…Carbon nanotubes (CNTs) are constructed with a high length‐to‐diameter ratio, which is significantly larger than that of any other material. These cylindrical carbon molecules have novel properties, including an extraordinarily high strength and good electrical and thermal conductivities; these properties make them potentially useful in many applications 4, 5. However, CNTs without surface modification are not easily evenly dispersed in polymer materials.…”

Carbon nanotubes (CNTs), with their high aspect ratio and exceptionally high mechanical properties, are excellent fillers for composite reinforcement if they are uniformly dispersed without aggregation. Combining the latex compounding and self-assembly techniques, we prepared a novel natural rubber (NR)/multiwalled carbon nanotube (MWCNT) composite. Before self-assembly, the MWCNTs were treated with mixed acid to ensure that the MWCNTs were negatively charged under an alkaline environment. The structure of the MWCNTs was tested with Fourier transform infrared spectroscopy. The properties of composites with different MWCNT loadings were characterized with transmission electron microscopy, scanning electron microscopy, thermogravimetric analysis, and tensile testing. The results indicate that the MWCNTs were homogeneously distributed throughout the NR matrix as single tubes and had good interfacial adhesion with the NR phase when the MWCNT loading was less than 3 wt %. In particular, the addition of the MWCNT led to a remarkable reinforcement in the tensile strength, with a peak value of 31.4 MPa for an MWCNT content of 2 wt %, compared to the pure prevulcanized NR (tensile strength ¼ 21.9 MPa). The nanocomposites reinforced with MWCNTs should have wide applications because of the notable improvement in these important properties. V C 2012 Wiley Periodicals, Inc.
