The impacts of the interfacial interaction modes and their strength on the filler dispersion and composites performances were clearly clarified.

This paper reports a simple, high-efficiency, and green approach for preparing high-dispersion silica-g-solution styrene butadiene rubber (SiO2-g-SSBR) through a solution mechanochemical reaction in a laboratory planetary ball mill. The condensation reaction between the hydroxyl groups on the silica surface and the siloxane groups of SSBR-g-3-mercaptopropyltriethoxysilane (MPTES) was verified. The results revealed that the chemical modifications of silica through an SSBR polymer matrix weakened the strong filler–filler interactions and enhanced the weak filler–polymer interfacial interactions simultaneously. Because of the dual role of SSBR-g-MPTES as a dispersant and rubber matrix, the modified silica showed high dispersion in the SSBR composites regardless of the compounding, storage, or vulcanization period. Additionally, the dispersion of modified silica was superior to that of silica modified through bis­(γ-triethoxysilylpropyl)-tetrasulfide (Si-69). Compared with the unmodified silica/SSBR composite, the performance of the composites was obviously improved, the rolling resistance decreased by 28.4%, wet skid resistance increased by 63.9%, and tensile strength increased by 40.4%.

The exploration of porous carbon materials with excellent electrochemical capacity is urgently needed for the development of the next generation of energy storage devices. Cage-like carbon nanomaterials have been extensively studied for their excellent capacitive properties, but the current preparation methods for carbon nanocages are generally costly. A simple and green preparation method for nitrogen-doped carbon nanocages is proposed in this study. In the synthesis process, the growth of the carbon nanocages is realized by using potassium chloride as a hard template, which can be removed by washing with hot water, avoiding the use of corrosive reagents and realizing the reuse of the template by recrystallization. The carbon materials exhibit unique nanocage morphology with macropores, which can provide fast ion diffusion pathways. Meanwhile, nitrogen doping enhances electrolyte ion interactions with carbon surfaces, leading to improved capacitances and rate capabilities. By the synthetical effect of the above characteristics, the specific capacitance reaches 251 F g À 1 at 0.1 A g À 1 and 201 F g À 1 at 10 A g À 1 . This work introduces a new method for preparing high-performance carbon electrode materials.[a] Dr.
