“…In the first place, PVA was modified with azide groups via the tosyl derivative. This azide derivative then reacted with propargyl alcohol or with an alkynyl derivative of galactopyranose to gain the final copolymers with hydroxyl methyl (PVATPHM) or protected galactosyl groups (PVATPGal) as substituents [74] . All the polymers showed thermal stability up to 200 °C.…”

Many new achievement developments for different industries have their origin in the basic science. Within the last years, this trend is gaining much attention since the interaction between both fields (scientific and industry) is increasing. This article presents some rational materials chemical modifications that were developed by the basic science and were, then, transferred to the productive sector. Conducting hydrophobic coatings for aerospace applications, hydrogels for the oil & gas industry as well as polymers for removal of heavy metal were some of the topics approached in the lab to solve industrial problems. Many times, nature is a great source of inspiration to produce new materials. In this sense, superhydrophobicity and superhydrophilicity (concepts closely related to our everyday life) were the bioinspiration for the development of membranes. These membranes were able to separate hydrocarbons and water, which found application in the treatment of subterranean water for oil & gas industry.

“…Such coordination compounds can be used for instance as catalysts in organic reactions, [23,24] stabilizers of sensitive explosives, [25] and other [26–28] . The complexation with metals is used for heavy metal sensing [29–31] and extraction [32–34] . Combination of two or more fragments of N‐containing heterocycles in a single molecule should increase the complexation ability further, [35] and if immobilized on the surface of a solid carrier, extraction of metal ions from solutions for content monitoring and purification of water, particularly industrial waste waters, becomes an important use.…”

Synthesis of 1‐(3‐(1‐substituted‐1,2,3‐triazol‐4‐yl)‐1,2,4‐triazol‐5‐yl)‐tetrazoles by Sequential Assembly of Azole Fragments

Only few efficient methods for the preparation of polyazoles containing three or four nitrogen atoms in each azole cycle exist. We have developed a novel synthetic strategy that allows the sequential assembly of 1,2,3‐triazole, 1,2,4‐triazole, and tetrazole fragments into a new stable polyazole. Along the novel strategy, some known procedures have been optimized to achieve better conversion, selectivity, and, in general, overall efficiency.

Thin films of poly(2,5‐benzimidazole) (ABPBI) polymer were prepared by the casting method, and sorption studies with aqueous CuSO4 solutions were performed. Surface interaction between Cu(II) and the membrane was studied using spectroscopic analysis (Fourier transform infrared, Raman and X‐ray photoelectron), showing a strong interaction through nitrogen groups of ABPBI and Cu(II). The best conditions for Cu(II) uptake were at pH = 5 and a soaking time of 60 min. In these conditions, the sorption isotherm was best fitted by the Langmuir equation and the maximum sorption capacity was estimated to be 1.5 mmol g−1. Due to sorption pH dependency, elution studies using hydrochloric acid solution were carried out, showing an almost complete removal of bonded Cu(II) when immersing the ABPBI membrane in the acidic solution. Surface morphology of membranes was studied using scanning electron microscopy–energy‐dispersive X‐ray spectroscopy, showing no major changes with sorption and elution experiments. These results show that ABPBI can be considered as an alternative polymer for the development of new materials for the removal of heavy metals. © 2022 Society of Industrial Chemistry.
