To obtain humidity-responsive antifungal fiber films,the experiment loaded humidity-responsive metal-organic framework material(MOF)copper metal-organic framework(FH)nanoparticles and bacteriostatic essential oil carvacrol(CAR)with ethyl cellulose(EC)and gelatin(GEL).The GEL/EC/CAR/FH humidity-responsive fiber films were prepared by electrospinning technology,the comprehensive properties of the fiber films were tested,and the controlled release behavior of CAR in the membrane was studied.The results show that the FH nanoparticles with a low mass fraction(<4%)have small effects on the microstructures of the fiber films and distribute uniformly in the fiber films.The addition of FH nanoparticles and CAR improves the tensile properties of the fiber films,and makes the fiber film have certain anti-fungal and anti-oxidation properties.The humidity response-control release study shows that FH particles could control the release of CAR on the fiber films by adjusting the humidity.When the mass fraction of FH nanoparticles is 4%,the CAR release rate(V)increases from 60.58%±0.23%to 99.68%±0.08%under the humidity change of 50%-90%.The GEL/EC/CAR/FH humidity-responsive anti-fungal fiber films have good performances,showing a good controlled release effect.
