Liquid‐like trisilanol isobutyl polyhedral oligomeric silsesquioxanes derivative (L‐POSS‐D) was synthesized with γ‐(2,3‐epoxypropoxy)propytrimethoxysilane (KH560) as corona and polyetheramine M1000 as canopy. Its structure and properties were characterized by FTIR, XPS, TGA and Rheology data. Epoxy nanocomposites with 0.0, 0.5, 1.0 and 2.0 wt% content of L‐POSS‐D were prepared. Tg of the nanocomposites improved 47.6°C higher than pure epoxy resin. Mechanical properties, including flexural strength and impact toughness, were improved markedly with L‐POSS‐D. The morphologies of impact fracture were studied by SEM. POLYM. COMPOS., 38:691–698, 2017. © 2015 Society of Plastics Engineers

We reported a solvent-free nanofluid based on MnSn(OH)6 crystallite with thread-like morphology through sulfuric-acid-terminated organosilanes as corona and polyether amine as canopy. The resultant is characterized by various analytical techniques and shows excellent solubility, good dispersity, improved processability and fluidity at room temperature in the absence of any solvents, which offer great potential in applications such as plasticizers with effects of toughening and reinforcement in nanocomposites. In addition, as a kind of plasticizer, it can also improve the Tg of its nanocomposites. These advantages of the flexible nanoscale thread of MnSn(OH)6 crystallite make it can be easily applied on the fabrication of high performance of nanocomposites.

Novel multifunctional graphene@Fe3O4 hybrid nanofluid with liquid‐like behavior at room temperature and low viscosity (5.5 Pa.s at 25°C) has been developed by using GO@Fe3O4 as a core, sulfuric acid‐terminated organosilanes as corona, and polyether amine as canopy. The obtained nanofluid has been extensively characterized by various analytical techniques. The content of graphene@Fe3O4 reaches up to 13.78 wt% in the hybrid nanofluid, which is a superparamagnetism material with specific magnetization of 0.39 emu/g. In addition, it shows excellent dispersion and exfoliation in solvents and polymer matrixes. It is then compounded with an epoxy resin for the development of liquid‐like graphene@Fe3O4 hybrid nanofluid/epoxy nanocomposites. It is found that liquid‐like graphene@Fe3O4 hybrid nanofluid/epoxy nanocomposites demonstrate better mechanical property than those of unmodified graphite/epoxy nanocomposites at the same fraction. For example, the multifunctional liquid‐like graphene@Fe3O4 hybrid nanofluid at 1.5 wt% improves the impact toughness of epoxy by 125%. This new interface modification also enhanced the Tg of neat epoxy from 98.37 to 129.46°C. POLYM. COMPOS., 37:3474–3485, 2016. © 2015 Society of Plastics Engineers
