Finite viscoelasticity of filled rubbers: the effects of pre-loading and thermal recovery

“…The mean diameter of CB particles is estimated as 30 nm, and the surface area of filler is about 80 m 2 /g [21]. Relaxation tests were performed at room temperature at three elongation ratios (λ = 1.2, λ = 1.4 and λ = 1.8) for samples made of the unfilled rubber, and at four elongation ratios (λ = 1.2, λ = 1.4, λ = 1.8 and λ = 2.0) for specimens made of the filled rubbers R1 and R2.…”

Finite Viscoelasticity of Particle-Reinforced Elastomers: the Effect of Filler Content

“…The mean diameter of filler particles (N-330) is estimated as 30 nm, and their surface area is about 80 m 2 N g -1 , see ref. [45] Table 1 presents detailed formulations of the compounds.…”

Micropatterning and Impedance Characterization of an Electrically Percolating Layer‐by‐Layer Assembly

“…One important aspect of this system, other than the substantial surface area of the electrodes, is that the conducting film is a percolating network that relies on electron and/or electrolyte movement between noncontacting CB nanoparticles. Based on previous transmission electron micrograph results [19,42], the incorporated CB volume fraction (ca. 30 -40 vol%), and allowable tunneling distances [42,43], we anticipate the average particle spacing to be on the order of the particle diameter.…”

“…Based on previous transmission electron micrograph results [19,42], the incorporated CB volume fraction (ca. 30 -40 vol%), and allowable tunneling distances [42,43], we anticipate the average particle spacing to be on the order of the particle diameter. In other words, the LbL film could be represented as a series of electrodes separated by 10 -30 nm gaps that are filled with electrolyte solution and a polyelectrolyte matrix.…”
