Effect of cooling rate on the microstructure absorption capacity of oil-based materials of graphene aerogels prepared by freeze casting at ambient pressure
Abstract Freeze casting is a very simple, inexpensive, and environmentally friendly method for the production of porous materials. In this method, the suspended particles are concentrated and compressed together as ice crystals grow so that the walls of particles will form between the ice crystals....

| 520 | |a Abstract Freeze casting is a very simple, inexpensive, and environmentally friendly method for the production of porous materials. In this method, the suspended particles are concentrated and compressed together as ice crystals grow so that the walls of particles will form between the ice crystals. After sublimation of ice, only the colloidal aggregate particles will remain without collapsing. In this study, by drying of graphene hydrogel using freeze casting under ambient pressure, the final pore size of graphene aerogels was controlled. Three types of graphene aerogels were prepared with three different freezing rates of 2, 1 and 0.64 °C/min. The results showed that by decreasing the cooling rate, the average pore size increased from 35.6 to 43.4 μm and the density decreased from 50 to 40 mg/$ cm^{3} $. The effect of freezing rate on the formation of controlled residual pores and some physical properties of graphene aerogels such as absorption capacity of gas oil, kerosene, cooking oil and ethanol was investigated. | ||

| abstract |
Abstract Freeze casting is a very simple, inexpensive, and environmentally friendly method for the production of porous materials. In this method, the suspended particles are concentrated and compressed together as ice crystals grow so that the walls of particles will form between the ice crystals. After sublimation of ice, only the colloidal aggregate particles will remain without collapsing. In this study, by drying of graphene hydrogel using freeze casting under ambient pressure, the final pore size of graphene aerogels was controlled. Three types of graphene aerogels were prepared with three different freezing rates of 2, 1 and 0.64 °C/min. The results showed that by decreasing the cooling rate, the average pore size increased from 35.6 to 43.4 μm and the density decreased from 50 to 40 mg/$ cm^{3} $. The effect of freezing rate on the formation of controlled residual pores and some physical properties of graphene aerogels such as absorption capacity of gas oil, kerosene, cooking oil and ethanol was investigated. © The Author(s), under exclusive licence to Springer Nature Switzerland AG 2022 |
