A commercially available flexible cover plate is selected as a comparative example test object, the blue light-proof flexible cover plate prepared according to the proportion and the preparation method in the embodiments 1-6 is selected as an example test object, and then performance tests are sequentially carried out according to the following test modes:
pencil hardness: the pencil hardness was measured by the method specified in JISK5600-5-4 using a surface measuring instrument (14 FW manufactured by New Toyobo scientific Co., ltd.) and a pencil for measuring pencil hardness (Mitsubishi UNI manufactured by Mitsubishi Pencil Co., ltd.). The measurement load was 750g, the measurement speed was 30mm/min, and the measurement distance was 5mm. The measurement was conducted 5 times, and the hardness of a pencil whose pass number exceeded 4/5 was used as the evaluation result.
Wear resistance: the steel wool is tested with a force of 1kg, a speed of 40 cycles/min, a test stroke of 40mm and a cycle of 2500 circles by using #0000 steel wool, and whether scratches exist in a friction area of the steel wool is observed.
Water contact angle: mu.L of the measurement liquid was dropped on the coating film, and the water contact angle 5 seconds after dropping was measured using an automatic contact angle meter (DM-501, manufactured by Kyowa Kagaku Co., ltd.). The angle is calculated by using a theta/2 method.
Bending test: examples and comparative samples were mounted in a U-tape dynamic folding apparatus (beijing malls precision equipment ltd) having two folding stages that rotated from 180 degrees (i.e., the sample was not bent) to 0 degrees (i.e., the sample is now folded) and were subjected to 100,000 cycles at a test rate of about 6 cycles/minute. The 3mm bend radius is determined by the gap between the two rigid plates in the closed state (0 degrees). No mandrel is used to guide the curvature (i.e., a free-form bend is used). Folding was performed at room temperature.
Table 1 shows the test results of the blue light-proof flexible cover plate prepared in the example of the present invention:
the transparent polyimide film is used as the flexible base layer, and the polymer formed by reacting the alkoxy isocyanide with the acid reagent is used as the reinforcing layer, so that the transparent polyimide film has high light transmission performance, ultrahigh hardness and bending resistance, the bending resistance times can reach more than 20 ten thousand, and the transparent polyimide film can be used for folding the display screen.
