“…As a result, the volume fraction of the interphase shrinks and its impact on the mechanical properties of the nanocomposite is neutralized. Additionally, induced by the agglomeration, the nanoparticles accumulate in specific regions and the other areas of the polymer remain unoccupied and their properties unaffected [24][25][26][27][28] . Therefore, homogenization of the nanoparticles distribution in a polymer matrix is of great importance.…”

The latex monodisperse polystyrene (PS) colloids are important for different advanced applications (e.g. in coating, biotechnology etc.). However, the size dependency of their structural properties that impacts the characteristics of the nanocomposites composed thereof is largely unknown. Here, monodisperse PS nanoparticles (MPNPs) are synthesized via emulsion polymerization in five sizes (50, 150, 300, 350, and 450 nm). The size of the PS MPNPs is tailored by controlling the reaction time, temperature, and amount of surfactant and initiator. the correlation between the particle size and structural properties of the PS MPNPs is established by different thermomechanical and optical characterizations. The smaller particles (50 and 150 nm) show a lower glass transition (T g) and thermal decomposition temperature and a lower Raman peak intensity. Yet, they trigger a higher iR absorption, thanks to a larger surface area. When incorporated in a polyvinyl alcohol (PVA) matrix, the smaller particles impart the resulting nanocomposite a higher tensile strength, and elastic and storage moduli. Whereas, they decline the elongation and loss factor. The very few examples of the MPNPs incorporated polymeric nanocomposites have been unstudied from this perspective. Thus, these tangible knowledge can profit scalable production of this kind of nanocomposite materials for different applications in a cost/energy efficient manner.

“…Otherwise, most of 2D sheet nanomaterials are easy to agglomerate in the matrix due to their high surface energy. [ 26 ] Therefore, it is essential to further improve the interfacial interactions between MoS 2 and PSR by modification. Nanocomposite embedded with functionalized MoS 2 nanosheets are good for enhancing interfacial compatibility.…”

Polysulfide rubber (PSR) is a versatile sealing material, but suffers from poor mechanical properties, which can be solved by increasing the crosslinking density and introducing fillers. In this study, functionalized molybdenum disulfide (MMoS2) by in situ incorporation with different thiol‐containing compounds is obtained. On the basis of the optimum content of 0.5 wt.%, the performance of MMoS2/PSR is systematically studied. The results show that the interfacial interaction between MMoS2 and the matrix is improved. In particular, PSR reinforced by MoS2 modified with polysulfide oligomer (MoS2‐LPO) behaves the most excellently. Its solvent resistance and crosslink density are also improved by 14.2% and 39.4%, respectively. The storage modulus of MoS2‐LPO/PSR is 394% higher than that of the unmodified one. This is attributed to the MoS2‐LPO playing the role of filler and large‐sized solid crosslinker at the same time. Through broadband dielectric spectroscopy (BDS), it is determined that MoS2‐LPO/PSR has the longest relaxation time due to the stronger interfacial interaction. In order to understand the effect of interfacial interaction between MoS2 and PSR on the properties of the composites more clearly, MoS2 modified with other functional groups are also discussed.
