Preparation method of anti-dry and anti-freezing hydrogel |
| abstract |
The dry-resistant and anti-freezing hydrogel prepared by the method has the dry-resistant performance that the hydrogel can still keep elasticity after being placed in a dry environment with the humidity of 11% -13% RH for 1-7 months in an open manner at room temperature, and the anti-freezing performance that the hydrogel can still not be frozen after being dried in a vacuum drying oven at-50 ℃ for 1-7 days, so that the hydrogel can keep good elasticity. The dry-resistant and anti-freezing hydrogel is used for loading the explosive detection reagent and is directly used for detecting corresponding explosive particles or liquid. Therefore, the problem that the detection device taking hydrogel as a substrate inhibits ion transmission because the detection device freezes below zero or loses water when used in a dry environment, and further the use of the detection device in a low-temperature and dry environment is limited is solved. |
