“…In ller-lled rubber composites, the rubber that is chemically or physically bound to the silica surface is called bound rubber. 16 The ller-rubber interfacial interaction can affect the bound rubber content. 35 Therefore, the measurement of bound rubber content is usually used to study the interfacial interaction between the ller and rubber.…”

“…14,15 In order to quantify the silica occulation extent during vulcanization at 150 C and 15 MPa, the differences in DG 0 between compounds and vulcanizates, dDG 0 , were calculated. 16,33 The DG 0 was the difference between the G 0 at 0.28% strain and 41.99% strain. As listed in Table 2, the dDG 0 values, which indicate the extent of silica occulation, 16,33 were lower in silica/F-SSBR composites than that in the silica/SSBR/ Si69 composite, signifying that the in situ modication of silica by the F-SSBR matrix could more effectively inhibit the formation of ller-ller networks during vulcanization at 150 C and 15 MPa.…”

“…More importantly, the in situ modication of silica by in-chain functionalized SSBR not only restrains the ller-ller networks but also enhances the ller-rubber networks during the mixing process, effectively inhibiting the reformation of ller-ller networks during storage and at the onset of vulcanization. [14][15][16][17] Interfacial interaction between silica and the functionalized rubber matrix can be regulated by interaction modes and their strength. The mode of interfacial interaction depends on the types of functional group, while its strength depends on the contents of the functional group.…”

To improve the utilization efficiency of recycled polycarbonate/acrylonitrile-butadiene-styrene (R-PC/ABS), we studied the mechanical, morphological, and rheological properties of R-PC/ABS with styrene-butadiene-glycidyl methacrylate (SBG), which was used to reinforce and toughen the R-PC/ABS through chemical compatibilization. Fourier transform infrared spectroscopy demonstrated that carboxyl and hydroxyl groups in R-PC/ABS reacted with epoxy groups in SBG to produce ester and ether groups. The results of scanning electron microscopy show that the domain sizes of the ABS particles decreased when the SBG content was 6 wt %; this demonstrated that the compatibility of the polycarbonate (PC) and ABS was improved after the addition of SBG. The results of the loss modulus of dynamic mechanical analysis were consistent with the morphological results, which reflected a better compatibility of PC and ABS in the modified samples. The introduction of SBG increased the molecular weight and entanglements; this improved the viscosity and storage modulus in the modified samples, as demonstrated by the rheological results. Furthermore, the mechanical properties were obviously enhanced, especially the impact strength, when the SBG content was 6 wt %; this was ascribed to the chemical reactions and improved compatibility after melt extrusion with SBG.

Silica serves as the primary filler in the fabrication of eco‐friendly tires, and achieving an optimal dispersion of polar silica within the natural rubber matrix is crucial for crafting high‐performance rubber composites. In this study, biodegradable surfactants polyethylene glycol (PEG) with molecular weights of 200, 400, and 800 were employed to modify silica. The modified silica was characterized by Fourier‐transform infrared spectroscopy; PEG‐modified silica with different molecular weights was compounded with Si69, a conventional silane coupling agent, in the formulation. This aimed to reduce Si69 dosage and mitigate the emission of volatile organic gases, such as ethanol, generated during the silanization reaction between Si69 and silica. Experimental findings revealed that compared with natural rubber composites containing six parts of Si69, the addition of PEG‐modified silica enhanced filler dispersion in the composite while reducing Si69 dosage by three parts. This led to accelerated vulcanization rates, effectively decreased energy consumption during production, and significantly improved wet slip resistance, while maintaining optimal rolling resistance. Rubber composites prepared with PEG800‐modified silica exhibited a 10% increase in elongation at break, a 12% increase in tensile product coefficient, and a 19% enhancement in wet slip resistance.Highlights Silica is modified by polyethylene glycol with molecular weight of 200, 400, and 800. The amount of silane coupling agent and VOC emissions are reduced. The interfacial bonding between silica and rubber matrix is enhanced. The tensile product coefficient and wet slip resistance are improved by 12% and 19%.
