The GMA, st and P (St-co-GMA) structural colors prepared in example 3 were characterized by FTIR, and the results are shown in FIG. 1. As can be seen from FIG. 1, 2980cm in the GMA curve -1 And 2930cm -1 The peaks at (a) are assigned to the saturated and unsaturated C-H bond stretching vibrations. 1730cm -1 And 1631cm -1 The peaks at (a) correspond to the stretching vibrations of the C = O bond and the C = C bond, respectively. 1450cm -1 And 1309cm -1 The peak at (a) is due to deformation vibration of the C — H bond. 1161cm -1 The peak is due to the stretching vibration of the C-O-C bondAnd (6) moving. 908cm -1 And 842cm -1 The peak at (A) belongs to the backbone vibration of the epoxy group. In the FTIR spectrum of curve b, 3078cm -1 And 3030cm -1 The peak at (b) is assigned to the stretching vibration of the unsaturated C-H bond on the benzene ring. 1450cm -1 And 1382cm -1 The peak at (A) belongs to the stretching vibration of the benzene ring skeleton. 1629cm -1 The peak at (a) is due to the stretching vibration of the C = C bond. As for FTIR spectrum (curve c) of P (St-co-GMA), the above peak was found to be 3078cm -1 、2980cm -1 、2929cm -1 、1730cm -1 、1450cm -1 、1382cm -1 、1309cm -1 、906cm -1 And 842cm -1 Are present. These results indicate that characteristic peaks of benzene ring, saturated and unsaturated C-H bond, C = O ester bond, unsaturated C = C bond, and epoxy group belonging to GMA and St are all present in the FTIR spectrum of P (St-co-GMA). Thus, FTIR spectroscopy indicated that P (St-co-GMA) copolymer had been successfully synthesized.
SEM images of P (St-co-GMA) -based structured yarn fabrics prepared in examples 1-5 are shown in FIG. 2. As can be seen from FIG. 2, the P (St-co-GMA) nanospheres prepared in examples 1-5 are spherical and can self-assemble into short-range ordered and long-range disordered amorphous photonic crystals on polyester fabric. The P (St-co-GMA) nanospheres of the remaining structural colors except the structural color of example 3 all had uniform particle size. In contrast, the structural color of example 3 is that two different P (St-co-GMA) nanospheres with narrow particle size distribution exist, and the nanospheres with small particle size are uniformly distributed in the nanospheres with large particle size. Further, specific particle size distributions of P (St-co-GMA) structural colors prepared in examples 1 to 5 are shown in FIG. 3. As can be seen from fig. 3, all the particle sizes of the P (St-co-GMA) nanospheres except the nanospheres of example 3 showed excellent monodispersity. The particle size of P (St-co-GMA) nanospheres varies with the mass ratio of St to GMA. The P (St-co-GMA) nanosphere with the mass ratio of 1; for P (St-co-GMA) nanospheres with a mass ratio of 2; the particle size of the P (St-co-GMA) nanospheres with mass ratios of 3. Although the average particle size of P (St-co-GMA) nanospheres with a mass ratio of 7. This result is in agreement with the SEM image of the structural yarn fabric with a mass ratio of 7. Therefore, P (St-co-GMA) nanospheres with different particle size distributions can be obtained by changing the mass ratio of St and GMA; and two P (St-co-GMA) nanospheres with different particle sizes and narrow distribution can be synthesized by a simple one-pot method.
FIGS. 4 and 5 are photographs of P (St-co-GMA) -based textured yarn dyed fabrics prepared in examples 1 to 5. As can be seen in FIG. 4, the P (St-co-GMA) nanosphere structural color on the polyester fabric varies with the mass ratio of St to GMA. The color of the P (St-co-GMA) nanospheres on the polyester fabric at a mass ratio of 2; when the mass ratio is 1; when the mass ratio is increased to 3; when the mass ratio is 7; the color of the P (St-co-GMA) nanospheres on the polyester fabric at a mass ratio of 4. P (St-co-GMA) nanospheres of St and GMA of different mass ratios can self-assemble to form amorphous photonic crystals on black polyester fabric to achieve five different colors. Fig. 5 is an enlarged view of fig. 4, and five different colors of blue, purple, red, denim blue and green on the polyester fabric can be clearly observed. The structural color of the P (St-co-GMA) nanospheres prepared in the different examples was uniformly distributed on the fibers, showing a uniform color.
To demonstrate the binding fastness of the P (St-co-GMA) structural colors prepared according to the present invention to the fabrics, the reflectance spectrum of the structural color of the fabrics prepared in examples 1 to 5, the reflectance spectrum of the structural color of the worn fabrics, and the reflectance spectrum of the structural color of the washed fabrics were measured, respectively, and the results are shown in fig. 6, 8, and 10. Comparative photographs of P (St-co-GMA) structure yarn dyed fabric before and after abrasion and before and after washing are shown in FIGS. 7 and 9, respectively.
As can be seen from fig. 6, P (St-co-GMA) nanospheres with different mass ratios of St and GMA on polyester fabric exhibited different reflectance curves. There is a maximum and/or minimum reflectance value in the curve for each color. At a mass ratio of St to GMA of 2, there is a reflectance peak at 430nm, with a reflectance of 6.05% corresponding to blue; when the mass ratio is 1; 3, there is no peak in reflectance for the mass ratio of 2, and there is a minimum reflectance at 550nm, indicating that there is light absorption in this region, which is exactly the green absorption region, and red is the complementary color to green, thus showing red; when the mass ratio is increased to 7; for a mass ratio of 4. For the structural color prepared in example 3, the presence of two different particle size nanospheres can produce a brighter color on the fabric.
As can be seen from fig. 7, the colors of the P (St-co-GMA) nanosphere structure yarn dyed fabrics prepared by different examples before and after abrasion are almost the same, and five colors have no obvious color difference before and after abrasion. While all reflectance curves in figure 8 are similar to those before wear (figure 7). The peak reflectance of these structural colors after abrasion varied slightly, all less than 0.5%. These results indicate that the P (St-co-GMA) nanosphere structural color on the polyester fabric has good color fastness to abrasion.
As can be seen from fig. 9, the structural colors of P (St-co-GMA) nanospheres with different mass ratios of St and GMA on the polyester fabric before and after washing were almost the same, indicating that the five structural colors did not change significantly after washing. While all the reflectance curves in fig. 10 were similar to those before washing (fig. 7), the reflectance at the peaks of these structural colors slightly changed after washing (less than 0.5%). These results indicate that P (St-co-GMA) nanosphere structured color polyester fabrics have good wash fastness. Therefore, the P (St-co-GMA) nanosphere structure color on the polyester fabric has good color fastness.
