A waterborne polyacrylate colloid with hard core and soft shell structure was synthesized with methyl methacrylate (MMA), styrene (St), butyl acrylate (BA), methacrylic acid (MAA) as monomers, diacetone acrylamide (DAAM) as crosslinking monomer and adipic acid dihydrazide (ADH) as crosslinking agent. By adjusting the glass transition temperature (T_g), the emulsion can be self?forming film without adding film forming additive at room temperature. The influence of DAAM?ADH crosslinking system on the properties of latex films was investigated. DSC and TGA analysis showed that the T_g and thermal stability of crosslinked latex films are higher than those of uncrosslinked films. When the mass ratio of DAAM in core?shell is 1∶2, the comprehensive performance of latex films is better than that distributed in core or shell alone. With the increase of DAAM content, the water absorption decreased from 18.99% to 4.38%, and the Gel Fraction increased from 79.30% to 90.84%. When the molar ratio of ADH/DAAM is 1.25, the water absorption reaches the lowest and the Gel Fraction reaches the maximum.

An improved ethylene glycol method was used to efficiently synthesize silver nanowires with a diameter of about 130 nm, a length of about 150 μm, and L/D was about 1 150 by adjusting the content of chloride ions, the amount of polyvinylpyrrolidone (PVP) and the reaction temperature. All raw materials are put in one time before the reaction, no need to use syringe pumps and other equipment to strictly control the content of components. The synthesized silver nanowires have high purity and few impurities. At the same time, it was purified by filtration and washed twice to obtain extremely pure silver nanowires, which is suitable for large?scale production. The conductive network of silver nanowires was constructed on the quartz glass substrate by spin coating. The results show that the light transmittance at 550 nm is 95.5%, the sheet resistance is 52.0 Ω/sq, and it have excellent photoelectric properties.
