“…As described before in this article, the crosslinking density is one key factor that the thermal property of nanocomposites is improved. The residual epoxy group in curved system and gel content are two indexes of crosslinking density. The less epoxy groups and higher gel content, the higher crosslinking density and better thermal and mechanical property the composite has.…”

Four kinds of liquid-like polyhedral oligomeric silsesquioxanes derivatives (liquid-Ds) were fabricated and characterized by FTIR, XPS, TGA, and Rheometer. The liquid-Ds/epoxy nanocomposites were prepared and their thermal resistance properties were tested by TGA. As a result, the thermal resistances properties were improved sharply and influenced by particle sizes, flow abilities, and bonding types of liquid-Ds. The glass transition temperature improved via adding liquid-Ds. The increase of crosslinking density was thought as an important factor to these improvements, which was studied by FTIR spectra and gel content of curved nanocomposites.

“…The 5% weight loss took place at 289 C for DUDCBz-EP matrix and for 5 wt% f-PFC/DUDCBz-EP composites at 322 C, which may explained due to the improved complexity and the formation of network structure brought by the reinforcement [41]. The char yield of 5 wt% f-PFC/DUDCBz-EP composites is about 18%, whereas that of DUDCBz-EP hybrid matrix was 11% and the enhanced char yield values of hybrid composites confirm the improved thermal stability [42].…”

In the present work, amine‐functionalized palm flower carbon (f‐PFC)‐reinforced 9, 10‐dihydro‐9‐oxa‐10‐phosphaphenanthrene‐urea diamine‐based cardanol benzoxazine‐epoxy hybrid (DUDCBz‐EP) composites have been developed and characterized. Differential scanning calorimeter analysis indicate that the amine‐functionalized palm flower carbon‐reinforced cardanol‐benzoxazine/epoxy (f‐PFC/DUDCBz‐EP) hybrid composites possess the higher values of glass‐transition temperature (Tg) than that of hybrid matrix (DUDCBz‐EP). Results from TGA infer that the PFC reinforcement significantly improves thermal stability and char yield according to the percentage weight. Morphological studies ascertain the amorphous structure and uniform as well as homogeneous dispersion of PFC reinforcement in the hybrid matrix. Contact angle measurements indicate that both the hybrid matrix and composites developed in the present work possess hydrophobic behavior. Data obtained from corrosion studies infer that the hybrid matrix as well as hybrid composites exhibit significant corrosion‐resistant behavior toward the surface of the steel specimen due to inherent characteristics of both benzoxazine and epoxy matrix, in addition to amine‐functionalized PFC. The results obtained from different studies, it is suggested that these hybrid matrix possess significantly improved properties and can be exploited for high‐performance cost competitive coatings for different industrial applications including protection of steel surfaces from corrosion.

Silsesquioxanes (SSQs), with the general formula, (RSiO1.5)n—where R stands for an organic group, such as alkyl, aryl, alkoxy, or H—are a type of molecular‐level organic/inorganic hybrid silica‐based material. These materials contain reactive or nonreactive organic moieties as well as inorganic Si–O–Si frameworks. In the past few years, extensive efforts have been made using SSQs to construct multifunctional nanocomposites with suitable properties for a range of applications. In this review, the recent various applications of SSQ‐containing hybrid materials are discussed, in addition to updates of the nanocomposite applications. Various physical structures and chemical reactions in SSQ‐based hybrid nanomaterials are emphasized with regard to applications in the field of polymer nanocomposites, catalysts, adsorption, sensors, and biomedicine. This review focuses on results reported in the recent five years (2013–2018).
