High Mass Residual Silica/Polybenzoxazine Nanoporous Aerogels for High-Temperature Thermal Protection

ACS Applied Nano Materials, Год журнала: 2024, Номер 7(16), С. 19527 - 19537

Опубликована: Авг. 6, 2024

High-performance thermal protection materials are urgently needed for applications under extreme conditions. Organic aerogels considered to be promising and efficient materials, but their low mass residuals have been the main obstacles limiting development application. Herein, by an in situ copolymerization of benzoxazine prepolymers N,N-dimethylformamide (DMF)-soluble silica (SiO2) precursors, polybenzoxazine (PBO) with increased SiO2 contents was formed, leading high residual SiO2/PBO (PBOS) dual-network nanoporous structures. The structures PBOS were obtained owing similar gelation cross-linking rates PBO SiO2, facilitated introduction ethanol temperature. resulting exhibited (75.96% Ar, increase approximately 26%; 52.23% air, 30%), considerably higher than those existing silicon-modified aerogels. PBOS-4 aerogel demonstrated excellent high-temperature insulation properties maintaining a back temperature 59.9 °C when exposed 1200 butane flame 600 s. Benefiting from stability, quartz fiber-reinforced (QF/PBOS-4) composite outstanding ablation resistance 1500 oxyacetylene s, linear 0.8 μm s–1 0.67 mg s–1, respectively. This study presents method producing high-performance suitable aerospace applications. By addressing inorganic–organic compatibility issues low-density this research enhances potential use PBO-based composites both civil military

Characteristics of Polybenzoxazine Aerogels as Thermal Insulation and Flame-Retardant Materials

Gels, Год журнала: 2025, Номер 11(2), С. 121 - 121

Опубликована: Фев. 6, 2025

Polybenzoxazine-based aerogels are a unique class of materials that combine the desirable properties aerogels-such as low density, high porosity, and excellent thermal insulation-with outstanding characteristics polybenzoxazines-such stability, water absorption, superior mechanical strength. Polybenzoxazines type thermosetting polymer derived from benzoxazine monomers. Several features polybenzoxazines can be retained within synthesized through them. The resistance polybenzoxazines, which withstand temperatures above 200-300 °C, makes their aerogel able to extreme environments. inherent structure rich in aromatic rings nitrogen oxygen atoms, imparts flame-retardant property. Their highly crosslinked provides solvents, acids, bases. Above all, molecular design flexibility, physical, mechanical, tubed suit specific applications. In this review, synthesis polybenzoxazine aerogels, including various steps such monomer synthesis, gel formation, solvent exchange drying, finally curing discussed detail. application these insulation is given importance. challenges future prospects further enhancing expanding utility also summarized.

Preparation and Testing of Polyethylenimine-Impregnated Silica Gel for CO2 Capture

Gels, Год журнала: 2024, Номер 10(6), С. 360 - 360

Опубликована: Май 23, 2024

This work studied the low-temperature sorption of carbon dioxide on impregnated silica gel. An impregnating agent was used polyethyleneimine. The content in gel matrix 33.4 wt.%. Material properties such as Brunauer–Emmett–Teller (BET) surface area, pore distribution, total volume, and thermal stability material were determined for sample. During measurement adsorption–desorption cycles, loss also determined. Due to decrease polyethyleneimine, capacity adsorbent CO2 decreased. It found that after 20th cycle, dropped by 3.15 wt.%, and, a result, adsorption almost half.
