“…Where m R represents the solar reflection coefficient of the composites and n 21 represents the relative refractive index of medium 2 relatives to medium 1. The refractive index of PVC is generally about 1.52, 37 and that of BaSO 4 is about 1.64 38 . It can be observed from the formula that the greater the difference between the refractive index of polymer matrix and inorganic filler, the higher the reflection coefficient of composites, and the higher the solar reflectance of composites.…”

Barium sulfate (BaSO4) has high reflectance throughout entire solar waveband (280–2500 nm). In this study, the melt blending method was used to incorporate BaSO4 into a plasticized polyvinyl chloride (PVC) matrix. The aim was to create composites that exhibit excellent reflective cooling performance in the solar waveband, specifically for use in building roofs. By increasing the content of BaSO4 from 0 to 200 phr, the total reflectance of the samples in the solar waveband showed significant improvement, rising from 6% to 48.8%. Furthermore, the thermal conductivity of the samples accordingly emerged apparent enhancement, increasing by 46.3% from 0.178 to 0.262 W m−1 K−1. Additionally, when subjected to irradiation by a solar simulator under a solar light intensity of 1000 W/m2 for 1 h, the indoor simulated irradiation temperature decreased from 41.4 to 27.4°C.Highlights White plasticized polyvinyl chloride (PVC) films with reflective cooling performance were prepared. The solar reflectance and cooling performance of PVC was enhanced by BaSO4. The reflectance mechanism of BaSO4 in PVC was established.

“…When these two curves coincide at a particular wavelength of the incident light, transmission can be allowed at around the same wavelength (Christiansen filter effect). Additionally, in all other wavelength regions, multiple-scattering occurs at the interface between the polymer and the liquid to create angle-independent color. ,− Figure h shows transmittance spectra of the P(EHMA- co -EGDMA) membrane without pores and the porous one immersed in toluene. Although the former appeared transparent, the latter gradually increased with increasing wavelength to exhibit λ max at 611 nm.…”

We fabricated porous polymeric membranes using the miniemulsion templating method to investigate the transmitted and scattered lights in terms of the Christiansen filter effect. This method made it possible to produce porous polymeric membranes with different refractive indices by polymerization of different monomers and copolymerization of monomers. When a membrane with an opencellular structure was immersed in a liquid, the transmitted light was observed at a wavelength where the refractive indices of the polymeric phase and the liquid matched. Angle-independent color derived from the scattered light could also be observed. When the porous membrane of poly(2-ethylhexyl methacrylate) (EHMA) was immersed in a mixture of different kinds of liquids, the maximum wavelength of the transmission (λ max ) changed according to the refractive index matching of the polymeric phase and the liquid, resulting in the change in coloration. Next, when the P(EHMA-co-EGDMA) membrane was immersed in a mixture of toluene and D-limonene, λ max and color varied depending on their mixing ratios. This coloration was controlled by temperature and the refractive indices of the polymeric phase and the liquid. Furthermore, we could estimate the refractive index of PEGDMA using λ max values obtained by immersing it into liquids with different refractive indices.

For flexible polyvinyl chloride (PVC) films with excellent mechanical performances and high transparency, the demand for antistatic properties is becoming increasingly urgent in textile and electronic fields. This study compares the effects of 60 phr bis (2‐(2‐butoxyethoxy) ethyl) adipate (DBEEA) with other five equal amounts of plasticizers on the conductivity, electrical stability, transparency, and mechanical properties of plasticized PVC. The infrared spectra of plasticizers indicate that there are unique ether groups exist in DBEEA. Then the calculated solubility parameters suggest the good compatibility between DBEEA and PVC. For conductivity, the volume resistivity and surface resistivity of the PVC sample with DBEEA (PVC/DBEEA) are 107 Ω· m and 1010 Ω, respectively, which are both lower by 3–4 orders of magnitude than that of other plasticized PVC. For electrical stability, the results indicate that PVC/DBEEA placed in air still maintains lowest resistivities. Under 10, 23, and 30°C, PVC/DBEEA keeps high and stable electrical properties. The similar refractive indices of DBEEA and PVC resin prepared by suspension method indicate good transparency for PVC/DBEEA. Moreover, PVC/DBEEA still has good mechanical property.
