Nitriles used to be known as cyanides; the smallest organic nitrile is ethanenitrile, CH3CN, (old name: methyl cyanide or acetonitrile – and sometimes now called ethanonitrile). 1835-49-0, formula is C8F4N2, Name is Tetrafluoroterephthalonitrile. Nitriles are found in many useful compounds, including methyl cyanoacrylate, used in super glue, and nitrile rubber, a nitrile-containing polymer used in latex-free laboratory and medical gloves.

Chen, Xiuling;Wu, Lei;Yang, Huimin;Qin, Yong;Ma, Xiaohua;Li, Nanwen research published 《 Tailoring the Microporosity of Polymers of Intrinsic Microporosity for Advanced Gas Separation by Atomic Layer Deposition》, the research content is summarized as follows. Tailoring the microporosity of intrinsically microporous polymers at the at. level is one of the biggest challenges in achieving high-performance polymeric gas separation membranes. In this study, for the first time, the Al2O3 at. layer deposition (ALD) technique was used to modify the microporosity of a typical polymer of intrinsic microporosity (PIM-1) at the at. level. PIM-1 with six ALD cycles (PIM-1-Al2O3-6) exhibited simultaneous high thermal, mech., pure- and mixed-gas separation, and anti-aging properties. The O2/N2, H2/N2, and H2/CH4 separation performances were adequate above the latest trade-off lines. PIM-1-Al2O3-6 showed CO2 and O2 permeabilities of 624 and 188 Barrer, combined with CO2/CH4 and O2/N2 selectivities of 56.2 and 8.8, resp. This significantly enhanced performance was attributed to the strong size sieving effect induced by the Al2O3 deposition.
