[0030] Put the silk fluff surface layer in ethanol with a bath ratio of 1:50 and ultrasonically clean it for 30 minutes, then dry it at 45°C for 2 hours, and put the dried silk fluff surface layer in deionized water with a bath ratio of 1:50. After ultrasonic cleaning for 30 minutes, place it at 80°C to dry for 6 hours, put the cleaned and dried silk fluffy surface layer into the reaction chamber of the atomic layer deposition equipment at 60°C, and purge it with nitrogen gas with a purity of 99.999% for 3 minutes. is 10sccm, and then Zn(CH with a purity greater than 97% at room temperature 3 ) 2 Send it into the reaction chamber in the form of pulses, the pulse time is 0.1s, the exposure time is 15s, and then purged with nitrogen gas with a purity of 99.999%, and the purging time is 30s, and then the H at room temperature 2 O is sent into the reaction chamber in the form of pulses, the pulse time is 1s, the exposure time is 20s, and then purged with nitrogen gas with a purit...
Embodiment 2
[0032] Put the fleece surface layer made of sheep wool at a bath ratio of 1:70 in propanol and ultrasonically clean it for 60 minutes, and then dry it at 80°C for 4 hours. After ultrasonic cleaning in deionized water for 60 minutes, place it at 100°C and dry for 8 hours. Put the cleaned and dried sheep wool fleece surface layer into the reaction chamber of the atomic layer deposition equipment at a temperature of 100°C, and blow it with nitrogen gas with a purity of 99.999%. Sweep 5min, flow is 30sccm, then will be in the Zn(C that is greater than 97% at room temperature 2 h 5 ) 2 It is sent into the reaction chamber in the form of pulse, the pulse time is 0.4s, the exposure time is 20s, and then purged with nitrogen gas with a purity of 99.999%, and the purge time is 35s, and then the glycol at room temperature is sent in pulse form into the reaction chamber with a pulse time of 3 s and an exposure time of 30 s, and then purging with nitrogen gas with a purity of 99.999% fo...
