“…These foams were special due to their tendency to self-order into periodic structures under gravity or confinement, resulting in excellent properties such as mechanical properties, thermal insulation, sound absorption, etc. [14][15][16]. At present, ordered foams could be generated by the bubbling technique or self-assembly methods [2,[17][18][19].…”

Environmentally friendly, flame-retardant, and relatively low-density (0.25-0.31 g cm −3 ) silicone foams (SiFs) were successfully obtained through dehydrogenation at room temperature (RT = 25.0 C). Moreover, a flame-retardant system for SiFs was obtained through a synergistic combination of platinum (Pt) compounds, superfine aluminum hydroxide (ATH), and ultrafine calcium carbonate (CC). The smoke suppression, flame retardance, mechanical properties, and thermal stability of SiFs with Pt compounds, ATH, and CC were tested using the limited oxygen index (LOI), UL-94 test, smoke density test, cone calorimeter, and thermogravimetry-Fourier transform infrared spectroscopy. With only 0.6 wt % Pt compounds, the pure SiF achieved the UL-94-V1 rating (3 mm thick), had an LOI value of 29.6%, and the maximum smoke density (MSD) was 6.5%. After adding ATH and CC, SiF composites could achieve the UL-94-V0 rating (3 mm thick), the LOI increase to 35.2%, and MSD decrease by 45%. Furthermore, the SiF with 0.6 wt % Pt compounds, 15.0 wt % ATH, and 15.0 wt % CC exhibited the optimal comprehensive properties for smoke suppression, flame retardance, mechanical performance, and thermal stability.

“…However, Hong and Lee's research object was room‐temperature‐cured silicone rubber, which has different cure mechanism with widely used high‐temperature‐vulcanized rubber. Song et al explored the influence of precuring time and saturation pressure on morphology of silicone rubber foam, and foams precured for 5 min owned minimum density (0.239 g cm −3 ) . But, the precuring process has to be adjusted along with material and specimen size, which is really inconvenient.…”

In spite of great concern on the wide application of silicone rubber foams, few works have been reported about easy‐operating foaming method. In this study, the effects of silica content and foaming process on the porous structure of high‐temperature‐vulcanized silicon rubber foams are evaluated, which are prepared by supercritical CO2 at different conditions, with fumed silica used for reinforcement. Silicone rubber foams with cell size in 8–120 μm, cell density in 105–108 cm−3, and density between 0.45 and 0.9 g cm−3 are prepared under different saturation conditions. The results show that increasing silica content can decrease cell size. It is also found that cell density improves exponentially with increasing saturation pressure and decreasing saturation temperature. Besides, it demands less than 1 h for specimens to reach equilibrium on thickness around 3 mm. All the results indicate that the porous structures of silicone foams can be tailored by foaming process parameters facilely and are predictable with fitted equation.
