Facile fabrication of low-content surface-assembled MXene in silicone rubber foam materials with lightweight, wide-temperature mechanical flexibility, improved flame resistance and exceptional smoke suppression

Flexible and fire-retardant silica/cellulose aerogel using bacterial cellulose nanofibrils as template material

“…S2a, ESI† for all PHRR values), yet remained comparable in PHRR to other reported aerogels. 49 It was suggested that the reason for the significant differences in PHRR between the various aerogels was due to the fractional chemical composition of the various silanes, where APTES increased the amount of combustible material in the form of three CH 2 and one NH 3 for every APTES reacted. In the case of MTMS-bCNF, a single CH 3 is added per attached silane, resulting in less combustible material per gram compared to APTES-bCNF; this was even more pronounced in the case of TEOS-bCNF as no additional combustible material was added.…”

Biomass-Derived Aldehyde and Aminated Graphene Oxide Reinforced Gelatin-Based Composite Films for Biopackaging via a Multipoint Cross-Linking Strategy

“…To further determine the variation in the primary amino group content of AGO samples, it was measured according to the principle of the diazotization reaction between the primary amino group and nitrous acid. , As shown in Figure d, the content of the primary amino group was 2.07 2.20, 2.99, 3.03, 2.95, and 1.51 mol/g, corresponding to AGO 1 , AGO 2 , AGO 3 , AGO 4 , AGO 5 , and AGO 6 , respectively. The amination modification was realized based on the reaction of the ethoxy group on the coupling agent KH-550 with the hydroxyl group on the surface of HGO (Figure a), so the variation in the primary amino group content of AGO increased in step with the change in the hydroxyl group content of HGO. − It could also be known that AGO 3 , AGO 4 , and AGO 5 had obviously a higher primary amino group content.…”

Transformation of Fly Ash-Based Oxide Particles into a Functional Silica–Alumina Aerogel and Its Potential Application as an Anti-icing Surface

“…There was an approximately 16.25% mass loss between 0 and 590 °C, referring to the removal of a small amount of physically absorbed water trapped in the material, as well as the oxidation of methyl groups (−CH 3 ) on the surface of the aerogel. 35,36 The mass loss continues with increasing temperature. The mass loss between 591 and 798 °C may result from the decomposition of the SA backbone due to thermal degradation.…”
