“…PFPMA with a short fluorinated side group was strategically used; despite their very low surface energies of 8–10 mN/m, acrylic polymers with long fluorinated side groups (number of fluorocarbon units ≥8) pose a potential environmental risk of bioaccumulation. − Nevertheless, the surface energy of poly(PFPMA) has a very low value of 12.6 mN/m . In addition, it was reported that a poly(PFPMA) coating increases the transmittance of a glass slide . Therefore, a broad range of the controllable surface and optical properties can be obtained by adjusting the ratio of PFPMA and the other monomers.…”

“…Fluorine-containing polymers are attractive materials that can satisfy the wettability and transparency requirements of surfaces because of their low surface energy and low reflective index. ,− Moreover, they exhibit outstanding properties such as unique water and oil repellency, self-cleaning capability, excellent thermal and chemical stability, and low dielectric constant. − On the other hand, the practical applications of fluorine-containing polymers are limited by their low solubility in common solvents, low compatibility with hydrocarbon polymers, low adhesion to any substrate, and high cost. Copolymerization with various monomers has been explored as an alternative to overcome these limitations. ,,− …”

Various fluorinated methacrylic copolymers (PFPMA- X) were prepared from 2,2,3,3,3-pentafluoropropyl methacrylate (PFPMA), methyl methacrylate (MMA), and three other nonfluorinated monomers. The surface and the optical properties of these copolymers were controlled by changing the ratio of PFPMA to MMA while keeping the sum of the concentration of the two monomers fixed at 60 wt %. The parameter X represents the nominal concentration of PFPMA in various feed ratios of all five monomers. Depending on the increase in PFPMA content in PFPMA- X, the surface energy varied proportionately between 26.7 (PFPMA content: 20 wt %) and 17.4 mN/m (PFPMA content: 60 wt %), which is well-correlated with the fluorine content on the surface. Interestingly, we found that all PFPMA- X-coated glasses showed different transmittance curves in the wavelength range of 300-700 nm, and the wavelength at which maximum transmittance was recorded shifted as a function of the copolymer composition. In addition, the surface coatings of PFPMA- X with higher fluorine contents increased the transmittance of bare glass by approximately 1-2%. Quite lower and tunable refractive indices were obtained depending on the fluorine content, and all PFPMA- X showed extremely lower birefringences. Freestanding films of PFPMA- X were also well-formed, indicating that they can be used in a wide range of applications.

“…Even though only 1 wt% PFPE-BP is used in the coating solution, the anti-reflective and anti-contamination abilities of the coating are significantly enhanced. This is because the PFPE moiety is aligned along the top surface of the coating layer 30 , thus affording the anti-reflective and anti-contamination surface properties of PFPE even at low loading. To confirm this, surface analysis using X-ray photoelectron spectroscopy (XPS) was performed ( Supplementary Fig.…”

Anti-reflection and anti-contamination coatings prepared from fluorinated polymers have widespread and important applications, ranging from protective films for corrosion resistance to high-tech microelectronics and medical devices due to their transparency, low refractive index, stain resistance, and antifouling properties. However, the application of existing coatings is hindered by low surface adhesion to the target substrate and weakness when exposed to mechanical stress or damage, resulting in significant limitations to their practical applications. Herein, we incorporate perfluoropolyether (PFPE) with benzophenone (BP) to develop an efficient coating material (PFPE-BP) possessing broadband anti-reflectivity, anti-contamination properties, excellent abrasion resistance, and stability under elevated temperatures and relative humidity. The presence of BP allows the coating materials to be homogeneously mixed with a commercial hard coating solution to uniformly coat the target substrate. Furthermore, UV light irradiation on the coating surface results in excellent adhesion between BP groups of PFPE-BP and the hard coating matrix.

“…Therefore, such copolymers should contain additional hydrophobic comonomers, such as styrene (S) or tricyclodecyl methacrylate, that have bulky and hydrophobic pendant groups. Accordingly, fluorinated − and silyl comonomers have been applied in several cases to increase hydrophobicity and decrease the moisture absorption of PMMA. However, despite numerous attempts, addressing the drawbacks of PMMA while maintaining its high transmittance remains a significant challenge.…”

Development of Poly(methyl methacrylate)-Based Copolymers with Improved Heat Resistance and Reduced Moisture Absorption

Poly(methyl methacrylate) (PMMA) is widely used as a transparent material for optical applications, owing to its high light transmittance. However, it exhibits poor heat resistance and high moisture absorption, leading to distortion and deformation upon exposure to elevated temperatures and/or moisture. These structural changes decrease the transparency of PMMA, critically limiting its applicability. In this study, we synthesized poly(methyl methacrylate-co-styrene-co-acrylamide) (PMSAm) as a reference polymer and introduced one of four different comonomers [N-phenylmaleimide (PMI), N-cyclohexylmaleimide (CHMI), allyltrimethylsilane (ATMS), or 2,2,2-trifluoroethyl methacrylate (TF)] as a means to improve heat resistance and reduce moisture absorption. Four series of PMMA-based random copolymers (PMSAm–PMI, PMSAm–CHMI, PMSAm–ATMS, and PMSAm–TF) were synthesized by conventional thermal radical polymerization. All of the polymers synthesized exhibited improved heat resistance, with PMSAm–CHMI exhibiting the highest glass transition temperature (T g = 122.54 °C) and 5% weight loss thermal decomposition temperature (T 5d = 343.40 °C) as well as the lowest thermal expansion coefficient (90.3 μm m–1 °C–1). The highest hydrophobicity was exhibited by PMSAm–TF, with a water contact angle of 78.9°, indicating higher hydrophobicity compared to that of pure PMMA (69.4°). More importantly, high transparency (∼90%) was exhibited by all of the synthesized polymers. Thus, our copolymerization strategy successfully addresses the limitations, i.e., low heat resistance and high moisture absorption, of conventional PMMA-based materials.
