Embodiment 1
[0021] Example 1: First, mix and stir 2130# thermosetting phenolic resin and ethylene glycol in a weight ratio of 1:1, then add phenolic resin and benzenesulfonyl chloride with a total weight of 6% of ethylene glycol and mix evenly to make a mixture; curing and molding : Pour the mixture into the mold, heat it at 50°C for 4 hours and 15 minutes for initial curing and molding; demould the sample after initial curing, carry out deep curing treatment on the sample, and heat it at the initial temperature of 60°C for 16 hours , then heat up to 80°C for 8 hours, 100°C for 16 hours, 120°C for 8 hours, 140°C for 16 hours, 160°C for 8 hours, 180°C for 16 hours for deep curing; 2 Carry out carbonization under protection, rise from room temperature to 600°C, keep warm for 1h, and the heating rate is 1.5°C / min. After carbonization is completed, cool down to room temperature with the furnace, and finally stop supplying N 2 To make porous carbon, see figure 1 , the pore volume of the porou...
Embodiment 2
[0022] Example 2: First, mix and stir 2130# thermosetting phenolic resin and ethylene glycol in a weight ratio of 1:2.3, then add phenolic resin and benzenesulfonyl chloride with a total weight of 6% of ethylene glycol and mix evenly to make a mixture; curing and molding : Pour the mixture into the mold, heat it at 50°C for 5 hours and 20 minutes for initial curing and molding; demould the sample after initial curing, carry out deep curing treatment on the sample, and heat it at the initial temperature of 60°C for 16 hours , then heat up to 80°C for 8 hours, 100°C for 16 hours, 120°C for 8 hours, 140°C for 16 hours, 160°C for 8 hours, 180°C for 16 hours for deep curing; 2 Carry out carbonization under protection, rise from room temperature to 600°C, keep warm for 1h, and the heating rate is 1.5°C / min. After carbonization is completed, cool down to room temperature with the furnace, and finally stop supplying N 2 To make porous carbon, see figure 2 , 5, the pore volume of the...
Embodiment 3
[0023] Example 3: First, mix and stir 2130# thermosetting phenolic resin and ethylene glycol at a weight ratio of 1:2.3, then add phenolic resin and benzenesulfonyl chloride with a total weight of 6% of ethylene glycol and mix evenly to make a mixture; curing and molding : Pour the mixture into the mold, heat it at 50°C for 5 hours and 20 minutes for initial curing and molding; demould the sample after initial curing, carry out deep curing treatment on the sample, and heat it at the initial temperature of 60°C for 16 hours , and then heated to 80°C for 8h, 100°C for 16h; 2 Carry out carbonization under protection, rise from room temperature to 600°C, keep warm for 1h, and the heating rate is 1.5°C / min. After carbonization is completed, cool down to room temperature with the furnace, and finally stop supplying N 2 To make porous carbon, see image 3 , the pore volume of the porous carbon obtained according to the preparation method of this example is 0.70 cm 3 / g.
