“…Figure 7(a) shows the transmittance of PP film before and after exposure, where there is a decrease in UV–VIS range, because the silicon oxide bond introduces a stronger absorption after exposure, 50 and the formed SiOx layer on top is nanoporous, which introduces a stronger diffuse reflection 51 . The reinforcements of red, green, blue, and yellow dyes conserve transmittance in at 650 nm for red, 550 nm for green, 450 nm for blue, and 570 nm for yellow as shown in Figure 7(b–e), which are in consistent with other reports on dye color filters on glass and PMMA in Table S1 19–22,26,52 . The transmittance values decrease by 10%–20% at these wavelengths after exposure, because the formation of SiO x layer introduces an absorption in UV–VIS range 50 .…”

“…Color filters are assembled into the essential component for analytical imaging for cameras on spacecraft. In comparison with glass‐based color filters, polymer‐based color filters are lightweighted, low‐cost, and not easily cracked, mainly including dyed polymers and pigment dispersed polymers 19–26 . Polymethyl methacrylate has been used as a polymer matrix for color filters with optical parameters shown in Table S1, while it exhibits poor thermal stability and weak mechanical strength compared to polyimide, and is not AO durable 26 .…”

Color filters and conductive films are widely used in spacecraft, while the lack of lightweight, flexibility, and atomic oxygen (AO) durability confine their potential applications in low earth orbit. In this study, a clear poly(amic acid) with an empirical 20 wt% polyhedral oligomeric silsesquioxane (POSS) solid content is designed for transparency and AO durability. Red, green, blue, and yellow dyes are reinforced with small amounts of 1–5 wt% in POSS polyimides for color filters. A silver nanowire network film is infiltrated onto the POSS polyimide for conductive film. Erosion depth upon hyperthermal AO exposure, surface morphology, surface chemistry, optical transparency, and conductivity have been systematically investigated. The erosion yields of all 20 wt% POSS polyimides decrease by an order of magnitude when subjected to 2.32 ± 0.05 and 2.39 ± 0.06 × 1020 atoms cm−2 AO fluences, as passivating SiOx networks are formed on film surface. The small‐amount dye additives into polyimides do not introduce obvious changes in AO durability and surface chemistry. The silver nanowire infiltrated POSS polyimide film shows a 65.7% transmittance at 550 nm and a sheet resistance of 8.50 ± 0.36 Ohm square−1. This study reveals promising attempts of POSS‐polyimide‐based color filters and flexible conductive films for potential space applications.

“…For the solvent resistance test, the sample was immersed for 10 min into PGMEA solvent and then dried, and the color difference of ΔE ab was subsequently determined. High thermal and solvent resistance properties, as indicated by a ΔE ab value of less than 5, are critical for dyes used in the commercial colorant process [ 10 , 11 , 16 , 17 ]. In the case of thermal properties, Cl-PAMOPC and Br-PAMOPC showed stable ΔE ab values of 4.93 and 3.43, indicating that these dyes can be used in commercial applications.…”

“…In addition, improved thermal and solvent stability in industrial solvents such as propylene glycol monomethyl ether acetate (PGMEA) must be realized for these dyes to be used in dye-based color filters [ 2 , 5 , 6 , 7 , 8 ]. If dyes are not stable in common industrial solvents such as PGMEA, then their application in color filters will be difficult [ 9 , 10 , 11 ]. Therefore, it is necessary to develop dyes with good thermal and solvent stability [ 10 , 11 ].…”

Novel yellow azo pyridone dye derivatives were synthesized for use in image-sensor color filters. The synthesized compounds have a basic chemical structure composed of azo, hydroxy, amide, and nitrile groups as well as different halide groups. New materials were evaluated on the basis of their optical, thermal, and surface properties under conditions mimicking those of a commercial device fabrication process. A comparison of their related performance revealed that, among the four prepared compounds, 5-((4,6-dichlorocyclohexa-2,4-dien-1-yl)diazenyl)-6-hydroxy-1,4-dimethyl-2-oxo-1,2-dihydropyridine-3-carbonitrile (Cl-PAMOPC) exhibited the best performance as an image-sensor color filter material, including a solubility greater than 0.1 wt% in propylene glycol monomethyl ether acetate solvent, a high decomposition temperature of 263 °C, and stable color difference values of 4.93 and 3.88 after a thermal treatment and a solvent-resistance test, respectively. The results suggest that Cl-PAMOPC can be used as a green dye additive in an image-sensor colorant.

Perylene Diimide Incorporated Polyurethane Polymer as Potential Colour Filter Material with Non‐fluorescent Property^†

et al. 2023

Comprehensive Summary A novel polyurethane polymer containing perylene diimide (PDI) unit and aniline segment, denoted as PU‐PDI, was designed and synthesized. Their tensile property and photophysical characteristic were investigated using various experimental and theoretical techniques. It is found that the elongation of PU‐PDIs can reach more than 1000%, indicating good tensile performance. Moreover, based on the photoinduced electron transfer mechanism, the aniline segments in polyurethane can quench the auto‐fluorescence of PDI unit to a negligible value, which overcomes the intractable fluorescence drawbacks of conventional colour filters. The non‐emissive characteristic, in combination with the good thermal stability and tensile property of PU‐PDI, provides a feasible design strategy to fabricate optical filters with high display quality.
