“…In order to increase above-mentioned parameters of polyurethanes, different strategies can be applied. Thermal stability and flame retardancy of PU composites can be improved by incorporation of specific comonomers into the polymer backbone or by blending with fillers of different nature (silsesquioxanes, borax, graphite, carbon fillers, silicates, metals, graphene, phosphates, and many others) [42][43][44][45][46][47][48][49].…”

A series of siloxane-silsesquioxane resins with Q 8 structures, as network nodes containing reactive Si-H groups in the siloxane backbone, connecting silsesquioxane moieties, were prepared in a hydrolytic condensation process and successfully functionalized by hydrosilylation of allyl alcohol. The proposed material being an alternative to the well-defined silsesquioxanes has been characterized and used for preparation of a series of polyurethane (PU)-based composites by simple reaction of 3-hydroxypropyl groups of siloxane-silsesquioxane resin with 1,6-diisocyanatohexane and subsequently with 1,6-hexanediol to get polyurethane composite. A series of composites based on PU and octakis(3-hydroxypropyldimethylsiloxy)octasilsesquioxane were prepared in the same manner to investigate the influence of the filler amount (1, 3 or 5%) and its structure on thermal properties of the obtained materials.

“…4, one can clearly see the emission of the same volatile decomposition products under the first decomposition stage (T max1 ) as compared to those observed for the starch-gpoly(phenyl acrylate) copolymers. This was confirmed by the presence of the following bands on the FTIR spectra gathered at T max1 which were responsible for the following inorganic species: CO 2 (at 670 and 2330-2365 cm [39][40][41]) has been indicated. It confirmed that the decomposition mechanism of starch-g-copolymers under the first decomposition stage was independent on the type of aromatic acrylate monomer used for the grafting process.…”

The effect of starch-g-copolymers structure on the thermal decomposition course under oxidative conditions by using the simultaneous TG/DSC/FTIR technique has been investigated. To those studies, two types of starch-g-copolymers obtained under the graft copolymerization process of aromatic acrylate monomers such as phenyl acrylate and benzyl acrylate onto starch have been chosen. The TG/DSC investigations confirmed that the course of the decomposition process of all studied copolymers under the heating and in the presence of air was similar and run through three large stages. TG/FTIR studies indicated on the same decomposition mechanism under the first decomposition stage, however, on the completely different decomposition mechanism under the second decomposition stage of the copolymers which was directly dependent on the structure of grafted polymer. In addition, it was also proved that the percent grafting of the copolymers has not influenced on its decomposition course and its decomposition mechanism. The grafting percent influenced only on the Dm in each decomposition stage and on the intensity in the emission of the volatile species.

“…e fire hazard of polymer materials is not only related to heat, but also to smoke. e smoke parameters obtained by cone calorimeter can also be used to evaluate the smoke suppression [29]. Figure 7 shows the smoke production rate (SPR) curves of neat TPU and TPU composites.…”

A novel lanthanum-doped MgAl-layered double hydroxide/graphene oxide hybrid (La LDH/GO) with a La3+/Al3+ molar ratio of 0.05 was successfully synthesized by the hydrothermal method. The structure and morphology of as-prepared samples were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and transmission electron microscopy (TEM). Then, La LDH/GO was added into thermoplastic polyurethane (TPU) to investigate its effect on flame retardancy, smoke suppression, and thermal stability of TPU composites. The cone calorimeter test (CCT) results indicated that the peak heat release rate (PHRR) and peak smoke production rate (PSPR) values of TPU with La LDH/GO decreased by 33.1% and 51% compared with neat TPU, respectively. Therefore, La LDH/GO can play a good role in flame retardancy and smoke suppression of TPU matrix during combustion. In the meantime, La LDH/GO could improve the char yield of TPU composites, which is attributed to the interaction between the physical barrier effect of GO and the catalytic effect of 0.05 La LDH.
