“…Discovered that adding POSS into polyamide improved its anti-permeability behaviour, and effectively reducing water and gas passage to suppress the corrosion process. 18 Chen et al 2020 effectively obtained a POSS modified aqueous polyurethane coating and reported that the POSS impacted the coating’s surface hydrophobicity and dielectric performance, and potentially lowered its conductivity as well. 19…”

Tetra functional epoxy resin namely tetraglycidyl 1,4’-bis (4-amine-phenoxy) sulphone benzene epoxy (TGBAPSB) was developed via 1,4’-bis (4-amine-phenoxy) sulphone benzene (BAPSB) and epichlorohydrin. TGBAPSB was reinforced with polyhedral oligomeric silsesquioxane (POSS) nanomaterial in various weight percentages (1–2 wt%) and polyamidoimidazoline (Aradur 140) was used as curing agent. FT-IR results validated the molecular structure of the synthesized POSS. Dynamic mechanical analysis (DMA) and thermogravimetric analysis (TGA) evaluated the thermo-mechanical and thermal behaviour of TGBAPSB epoxy matrix and its organic-inorganic hybrid epoxy nanocomposites (TGBAPSB/POSS). X-Ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM) investigated the surface morphological behaviour of the organic-inorganic hybrid epoxy nanocomposites. TGBAPSB epoxy resin with optimized POSS reinforcement exhibited excellent thermo-mechanical, thermal, mechanical, dielectric, and water absorption properties, making it a suitable material for advanced high-performance applications.

“…They may also be used as antioxidants [ 23 ] or nanoparticle dispersants for plastics [ 24 , 25 ]. Cage siloxanes have been studied as functional and processing additives for polyolefins, e.g., polyethylene or polypropylene [ 26 ], as well as other thermoplastics, including PES [ 27 ], PPS [ 28 ], PEO [ 29 ], or different grades of polyamide (PA) [ 30 ]. The effect of these additives on the properties of the base polymer is highly dependent on the level of dispersion of the additive within the polymer matrix and the CS–matrix interactions (either macroscopic or molecular level ones).…”

Why POSS-Type Compounds Should Be Considered Nanomodifiers, Not Nanofillers—A Polypropylene Blends Case Study

et al. 2021

In this work, a seriTables of silsesquioxanes (SSQ) and spherosilicates (SS), comprising a group of cage siloxane (CS) compounds, was tested as functional additives for preparation of isotactic polypropylene (iPP)-based nanocomposites and discussed in the aspect of their rationale of applicability as such additives. For this purpose, the compounds were prepared by condensation and olefin hydrosilylation reactions. The effect of these cage siloxane products on properties of obtained CS/iPP nanocomposites was analyzed by means of mechanical, microscopic (scanning electron microscopy-energy dispersive spectroscopy), thermal (differential scanning calorimetry, thermogravimetry), thermomechanical (Vicat softening point) analyses. The results were compared with the previous findings on CS/polyolefin composites. The role of CS compounds was discussed in terms of plastic processing additives.

Polyhedral oligomeric silsesquioxane (POSS) is a family of organic/inorganic hybrid materials with specific molecular symmetry, and shows great potential in the structural design of nanomaterials. Here, a “bottom‐up” strategy is designed to fabricate 3D interconnected Si/SiOx/C nanorings (NRs) via AlCl3‐assisted aluminothermic reduction using dodecaphenyl cage silsesquioxane (T12‐Ph) as the building block. In this process, AlCl3 acts as both a liquid medium for reduction, and significantly as the catalyst to the cross‐linking of phenyl groups in T12‐Ph. The obtained Si/SiOx/C NRs exhibits uniform diameter of ≈165 nm and well distribution of C and Si elements. The unique ring‐like structure of Si/SiOx/C NRs makes it have great application potential in the field of lithium ion batteries. Notably, Si/SiOx/C NRs exhibits superior high‐rate capacity and good cycle stability when used as anode for LIBs. More excitingly, Si/SiOx/C NRs can deliver a high reversible capacity of 517.9 mA h g−1 at ultra‐low temperature of −70 °C, and the capacity retention as high as ≈50% of that at 25 °C. This work not only broadens structural design of carbon‐based nanomaterials but also provides more possibilities for the application of POSS.
