“…Lesser known are Polyvinyl Butyral (PVB) and Ethylene Vinyl Acetate (EVA), which are utilized in laminated panes and windows as interlayer materials [3]. However, typical polymer properties like high thermal expansion, low stiffness, low thermal conductivity, and low wear and scratch resistance have led to different approaches to using fillers to create a transparent composite with enhanced properties [4][5][6][7][8].…”

In this paper, the dynamic mechanic and optical properties of composites made of Polyvinyl Butyral (PVB) and Micro Glass Flakes (MGF) with matching refractive indices (RIs) are investigated. The composite is produced by a slurry-based process using additional blade casting and lamination. It can be shown that a high degree of ordering of the MGF in the polymer matrix can be achieved with this method. This ordering, combined with the platelet-like structure of the MGF, leads to very efficient strengthening of the PVB with increasing content of the MGF. By carefully adjusting the RIs of the polymer, it is shown that haze is reduced to below 2%, which has not been achieved with irregular fillers or glass fibers.

“…However, when PMMA-glass fibre composites are fabricated, strong variations in transmittance as a function of wavelength and temperature are observed. In a detailed study of glass fibre-reinforced epoxy, Iba et al 160 demonstrated that through careful synthesis, a broad range of optical and mechanical properties is feasible, with the general trend that the light transmittance improves at the expense of the specific modulus and tensile strength, as shown in Fig. 47.…”

Fibre-reinforced hydrogels with high optical transparency are an emerging composite material with great promise to enable new applications, such as a transparent wound dressing with custom tuned mechanical properties that provides desirable mechanical and physical properties along with optical clarity for facile wound inspection. Stand-alone hydrogels are an important class of materials comprising a cross-linked polymer network surrounded by a water matrix. However, their mechanical properties are typically very modest compared with other materials. While significant research is going on in parallel in the fields of hydrogels and reinforcement fibres, researchers are only starting to scratch the surface of the possibilities of combining the two. This report provides a review of natural and synthetic reinforcement fibre research with special emphasis placed on nanofibres. These provide the added benefit of transparency by being much smaller than the wavelength of visible light. A review of hydrogel materials is also presented. The mechanical properties, optical properties and biological functionality of hydrogel systems are also described. Ocular, load-bearing tissue, wound management and sensing/ device applications are all discussed. Transparent fibre-reinforced hydrogels provide a compelling potential solution to enable advanced functionality, in particular in the wound care and optical application areas.

“…Some inorganic UV-absorbents like ZnO do not migrate into polymer matrix; what's more, they have thermal-and photo-stability [10,11]. While almost all inorganic/polymer composites are opaque, except that the refractive index (Rl) of filler is hardly any difference with the matrix polymer or the size of the filler must be nanometer scale with a relatively low addition [12][13][14].…”

With development of high-power white light LED, people pay more attention to the reliability and security of packaging materials. Epoxy resins, as a main material for LED potting compound, remains to improve its thermal conductivity and ultraviolet shielding efficiency. ZnO nanoparticles were found to be well in ultraviolet (UV) absorption and good conductor of heat. In the present work, The ZnO nanoparticles were prepared by simple precipitation and calcination, presented high visible-light transparency and well ultraviolet shielding at low concentration. The ZnO/epoxy nanocomposite solution was prepared by mixing ZnO powders with epoxy resins using the ultrasonic technique, and then the composite film was prepared by spin coating technique. The results indicated that the ZnO/epoxy nanocomposite film kept high visible transparency and high ultraviolet shielding at the condition of 5wt% addition. The ZnO nanoparticles obviously enhanced UV -shielding efficiency of the epoxy resins.
