Embodiment 1
[0029] The first step, pretreatment of porous CuAlMn shape memory alloy samples
[0030] Firstly, under the protection of high-purity argon, the quenched porous CuAlMn shape memory alloy sample was thermally cycled 5 times in the temperature range from room temperature to 350 °C, then placed in an ultrasonic cleaner, cleaned with deionized water for 20 minutes, and then washed with anhydrous Wash with ethanol for 20 minutes until the stains adhered to the outer surface of the porous CuAlMn shape memory alloy sample and the inner surface of the hole are removed;
[0031] The second step, the preparation of polystyrene-2-methyltetrahydrofuran solution
[0032]First, polystyrene: 2-methyltetrahydrofuran=1:4 according to the mass ratio, get the required amount of 2-methyltetrahydrofuran solvent, weigh the polystyrene of the proportioning amount at the same time, then put the weighed polystyrene Mix ethylene and 2-methyltetrahydrofuran solvent, and stir with a magnetic stirrer for...

[0038] The first step, pretreatment of porous CuAlMn shape memory alloy samples
[0039] First, under the protection of high-purity argon, the quenched porous CuAlMn shape memory alloy sample was thermally cycled 5 times in the temperature range from room temperature to 350 °C, then placed in an ultrasonic cleaner, cleaned with deionized water for 25 minutes, and then washed with anhydrous Wash with ethanol for 25 minutes until the stains adhered to the outer surface of the porous CuAlMn shape memory alloy sample and the inner surface of the hole are removed;
[0040] The second step, the preparation of polystyrene-2-methyltetrahydrofuran solution
[0041] First, polystyrene: 2-methyltetrahydrofuran=1:5 according to the mass ratio, take the required amount of 2-methyltetrahydrofuran solvent, weigh the polystyrene of the proportioning amount at the same time, then put the weighed polystyrene Mix ethylene and 2-methyltetrahydrofuran solvent, and stir with a magnetic stirrer for...
Embodiment 3
[0049] The first step, pretreatment of porous CuAlMn shape memory alloy samples
[0050] First, under the protection of high-purity argon, the quenched porous CuAlMn shape memory alloy sample was thermally cycled 6 times in the temperature range from room temperature to 350 °C, then placed in an ultrasonic cleaner, cleaned with deionized water for 25 minutes, and then washed with anhydrous Wash with ethanol for 25 minutes until the stains adhered to the outer surface of the porous CuAlMn shape memory alloy sample and the inner surface of the hole are removed;
[0051] The second step, the preparation of polystyrene-2-methyltetrahydrofuran solution
[0052] First, polystyrene: 2-methyltetrahydrofuran=1:6 according to the mass ratio, get the required amount of 2-methyltetrahydrofuran solvent, weigh the polystyrene of the proportioning amount at the same time, then put the weighed polystyrene Mix ethylene and 2-methyltetrahydrofuran solvent, and stir with a magnetic stirrer for ...
