preparation example Construction
[0042] The preparation method and performance of composite material CMC among the present invention are introduced as follows:
[0043] A kind of preparation method of composite material CMC, comprises the steps:
[0044] S1: the nano-Fe 3 o 4 Ultrasonic dispersion in a three-necked flask containing deionized water to form Suspension A;
[0045] Dissolve MOFs and CS in a beaker and stir well to form a stable suspension B. The mass ratio of MOFs and CS is 1:4 to 4:1. In practice, the mass ratio of MOFs and CS can be selected as 1:4 or 1:2 , 1:1, 2:1 or 4:1;
[0046] S2: According to Fe 3 o 4 The mass ratio of CS to CS is 1:4~4:1, inject the suspension B into the suspension A drop by drop, and stir rapidly to form a uniform and stable suspension, and then add pure N 2 The reaction solution is completely deoxygenated by bubbling, and during specific implementation, Fe 3 o 4 The mass ratio to CS can be selected as 1:4, 1:2, 1:1, 2:1 or 4:1;
[0047] S3: Add the initiator ...
