Optical properties of sulfur copolymers for infrared applications

Nonlinear optical properties of chalcogenide hybrid inorganic/organic polymers (CHIPs) using the Z-scan technique

“…The sulfur-containing polymers we have prepared, possess high refractive index (n>1.7) due to the high content of S-S bonds and the large polarizability of the sulfur electrons [12]. In the case of poly(S-r-DIB) compounds, the refractive index can be increased as the wt% of sulfur is increased [7,13]. In Fig.…”

Sulfur copolymers for IR optics

“…Furthermore, the refractive indices of these polymers range from 1.78 to 1.85, which is much higher than the refractive index of standard optical polymers. 6 Materials with higher refractive indices bend light more, which enables thinner lenses and thus lighter, smaller optical systems. Next, we will continue to study the mechanical and optical properties of the copolymer at different temperatures.…”

Influence of pozzolans on plant oil‐sulfur polymer cements: More sustainable and chemically‐resistant alternatives to Portland cement

“…Multiple processing methods are effective for HSMs, including hot-pressing, 4 melt-casting, 5 and nucleophileinduced interfacial bonding, 6 which make HSMs particularly attractive in additive manufacturing applications. HSMs have shown promise in applications ranging from lithium-sulfur batteries [7][8][9][10][11][12][13][14][15][16] and IR transparent lenses, [17][18][19][20][21][22][23] to adhesives, 24 fertilizers, [5][6][7][8][9][10][11] and adsorbents for environmental remediation. [25][26][27][28][29][30][31][32][33] Elemental sulfur, comprising principally cyclo-S 8 , is a low-value coproduct of petrochemical industrial processes that chemically remove S-atoms from petrochemicals to prevent poisoning of the noble metal catalysts employed in later steps and to prevent acid rain that results from burning sulfur-containing fuels.…”
