This invention provides an electrochromic material, its preparation method, and its application. The structural formula of the electrochromic material is shown below: AR1 is a group represented by R1 or R3; AR2 is a group represented by R2 or R6; AR3 is selected from any one of R3, R4, and R5; AR4 is a group represented by R2; n is the degree of polymerization, and n is 4–35. This invention uses an arylation polycondensation process to prepare four high-performance solution-processable electrochromic materials: TTP, TEP, TPP, and PBP3P. Using these electrochromic materials as raw materials, high-performance patterned electrochromic camouflage devices are prepared using mask spraying. Nylon filter membranes with different pore sizes are introduced into the device structure to adjust the device's transmittance and achieve better camouflage effects.

The utility model discloses a rotating shaft module for firearms, which is convenient to mount and dismount. A rotating shaft module for firearms comprises a shaft sleeve, a shaft mortise and tenon and a rotating shaft, a stepped hole is formed in the shaft sleeve, the shaft mortise and tenon is in clearance fit with the large-diameter section of an inner hole of the shaft sleeve, a clamping shaft is arranged on the shaft mortise and tenon in the radial direction, an upper groove and a side groove are formed in the shaft sleeve and correspond to the clamping shaft, the upper groove is communicated with the side groove, the clamping shaft enters the upper groove, and the clamping shaft enters the side groove. The side face groove is used for being matched with the clamping shaft and limiting the axial limit position of the shaft clamping tenon, the rotating shaft is in clearance fit in the small-diameter section of an inner hole of the shaft sleeve, and a limiting head is arranged at one end of the rotating shaft, located in the large-diameter section of the inner hole of the shaft sleeve and limiting the axial position of the rotating shaft. The other end of the rotating shaft extends out of the shaft sleeve, and the end, extending out of the shaft sleeve, of the rotating shaft is used for being connected with a rotating component of a firearm.

The invention discloses a printing process of a polyester, vinylon and cotton blended camouflage fabric with a reverse anti-color-transmission function. The production process comprises the following steps: a pretreatment process, rolling of a waterproof agent on a single side of the reverse side, a printing process, baking and shaping, reduction and soaping, an after-finishing process and the like. According to the process, a waterproof agent is rolled on the reverse side of the fabric, so that the reverse side of the fabric has a water-repellent effect, color paste permeation is weakened, and reverse side permeation of dye in the subsequent printing process is prevented; the dyeing effect of the printing paste on the front side of the fabric is not influenced, and the permeation of the paste is effectively weakened, so that the printing effect that the front pattern is clear and the back is non-transparent is achieved; meanwhile, in the reduction soaping step, a waterproof agent on the reverse side of the fabric effectively maintains the printing effect, and the stability and quality of the printing effect are ensured. By adopting the disperse / vat dye one-paste printing process, the printed fabric is good in hand feeling and air permeability, five-color camouflage fabric printing is achieved, colors are rich, the camouflage effect is good, and the requirements of military garments are better met.
