“…Upon macroscopic strain application to the composite material, a strain amplification effect arises [35,36]. Based on the strain amplification factor and "particle phase" structural effects, Song and Zheng proposed the "two-phase model" [37][38][39]. This model decomposes the rheological response of the composite system into the sum of independent contributions of the polymer matrix and filler particles to the viscoelasticity, specifically expressed as 𝐺 * 𝜑, 𝜔 𝐴 𝜑 𝐺 * 𝜔 𝐺 * 𝜑, 𝜔 , where 𝐺 * represents the matrix modulus, 𝐺 * represents the filler phase modulus, and 𝐴 𝜑 represents the strain amplification factor.…”

To improve heat dissipation capability and enhance mechanical properties, a series of silica aerogel (SA) and modified glass fiber (GF)-filled SBR composites were prepared. It was found that the addition of SA successfully reduced the thermal conductivity of SBR by 35%, owing to the heat shield of the nanoscale porous structure of SA. Moreover, the addition of modified glass fiber (MGF) yielded a significant increase in the tensile and tear strength of SBR/SA composite rubber of 37% and 15%, respectively. This enhancement was more pronounced than the improvement observed with unmodified GF, and was attributed to the improved dispersion of fillers and crosslinking density of the SBR matrix. Rheological analysis revealed that the addition of SA and MGF weakened the ω dependence. This was due to the partial relaxation of immobilized rubber chains and limited relaxation of rubber chains adsorbed on the MGF. Furthermore, the strain amplification effect of MGF was stronger than that of GF, leading to a more pronounced reinforcing effect.

Rubber nanocomposites exhibit strain softening under large‐amplitude oscillation shear and large‐strain cyclic tension while the softening behaviors are hard to regulate in industry. Herein, an oligomer deep eutectic solvent (DES) synthesized from polyethyleneglycol and tetrabutylammonium bromide is used to mediate the vulcanization and softening behaviors of natural rubber (NR) gums and their nanocomposites. The results show that DES could accelerate NR vulcanization and improve crosslinking density. For the hydrophilic silica nanocomposites, DES could greatly reduce tanδ and weaken weak strain overshoot accompanying Payne and lower percentages damping accompanying Mullins effects. The effects in nanocomposites filled with hydrophilic/hydrophobic silica and carbon black are investigated and compared. The investigation provides a new way for tailoring elasticity and dissipation of vulcanizate nanocomposites filled with hydrophilic silica.
