“…For example, fluorinated polymers have very high densities but very low intrinsic refractivity and therefore very low refractive indices. The densities of many polymers containing aromatic rings [42][43][44][45][46] are not very high but they have large intrinsic refractivity and therefore high refractive indices.…”

“…For obtaining high refractive index, element should have high mean polarizability and low molar volume, co-polymerization of monomers and homopolymers that have n > 1.6 can also lead to polymers having a high refractive index. To obtain polymers with high refractive index and Abbe number, polymers incorporating such characteristic structures as an aromatic group, a halogenated aromatic group [42][43][44][45][46] and an alicyclic condensed ring were synthesized, but refractive index and Abbe number values were improved moderately.…”

“…The direct consequence of their being lightweight would help obtain high-powered lenses, which is not possible with glass. The optical plastics would then be a preferred choice because the high-powered glass lenses (>3.0 D) would be much heavier especially for children [2].…”

Optical plastics have been the priority area of research for material scientists worldwide, mainly, to find alternative materials to glass, a conceptual optical material in use over the years. There are numerous advantages of using plastics for optical applications, in particular for ophthalmic applications over glass. Recently, the researchers have been putting their efforts to develop novel plastic materials to meet requirements of ophthalmic industries. The present review compiles the recent developments in the area of optical plastics. The aim is to present the current state-of-the-art in the field, besides analyzing the various aspects of developing optical plastics. The review presents various possible approaches to achieve the desired properties e.g. high refractive index of the optical plastic materials.

“…A large Abbe's number corresponds to low dispersion in the refractive index. 20 Highly refractive materials generally exhibit a small Abbe's number. [8][9][10][11] Sulfur-containing polymers are presumed to have a high refractive index from the Lorentz-Lorentz equation, [8][9][10][11][12] because of high atomic refraction of the sulfur atom.…”

Several sulfur-containing acrylate polymers were developed for a high refractive index with high transparency and good processing performance for thin films. A series of poly(methacrylate)s were synthesized by radical polymerization, in which thin films are coated on a quartz substrate for optical characterization. One, two and three sulfur atoms were bound into acrylate monomers and thermally copolymerized with methyl methacrylate. An alicyclic structure was used to achieve a dense molecular volume of the sulfur-containing monomer. Refractive index was measured under visible light. The index linearly increased with the sulfur-containing monomer content of the copolymer. Each homopolymer was predicted by an extrapolation method, resulting in a high refractive index of 1.624-1.725 at 589 nm. An Abbe's number of B30 was recorded for most sulfur polymers, indicating low wavelength dispersion of the index. A polymer with dipolar functionality displayed an Abbe's number of 40.9. High optical transparency of films was observed at the wavelengths of the index measurement. All polymers were thermally stable up to B250 1C and exhibited glass transition around 100 1C.

Optical nanocomposites based on transparent polymers and nanosized pigment particles have usually been produced at low particle concentrations due to the undesirable optical scattering of the pigment particles. However, the contribution of the particles to many physical properties is realized at high concentrations. In this study, nanocomposites were prepared with transparent polystyrene (PS) and organophilic CeO 2 nanoparticles using various compositions in which the particle content was up to 95 wt%. The particles, capped by 3-methacryloxypropyltrimethoxysilane (MPS), were dispersed into PS and the transmittance of the spin-coated composite films was examined over the UV-visible region.When the particle concentration was <20 wt%, the transmittance of the films showed a first-order exponential decay as the Rayleigh scattering theory proposes. However, a positive deviation was observed from the decay function for higher particle contents. The improvement in transmittance may be a consequence of interference in the multiple scattering of light by the quasi-ordered internal microstructure that gradually develops as the particle concentration increases.
