by In recent years, materials researchers experimenting with ceramics have begun adding an oxidized form of graphene to the mix to produce ceramics that are stronger, more durable, and more resistant to fracture, among other desirable properties. Researchers at the National University of Singapore (NUS) have developed a new method using ultrasound to more evenly distribute graphene oxide (GO) in ceramics, according to a new paper published in the journal ACS Omega. And as an added bonus, they collaborated with an artist who used the resulting ceramic tiles to create a unique art exhibition at the NUS Museum, a striking fusion of science and art.
As previously noted, graphene is the thinnest material ever known, consisting of a single layer of carbon atoms arranged in a hexagonal lattice. This structure gives it many unusual properties that hold great promise for real-world applications: batteries, supercapacitors, antennas, water filters, transistors, solar cells and touch screens, to name a few.
In 2021, scientists discovered that this wonderful material could also provide a solution to the fading of many artistic masterpieces. For example, several oil paintings by Georgia O’Keeffe housed at the Georgia O’Keeffe Museum in Santa Fe, New Mexico, over decades developed tiny, pin-sized, almost water-like blisters. ‘acne. Conservators have found similar deterioration in oil-based masterpieces across all eras, including the works of Rembrandt.
Van Gogh Sunflower The series has faded over the past century due to constant exposure to light. A 2011 study found that the chromium in Van Gogh’s favorite chrome yellow reacted strongly with other compounds like barium and sulfur when exposed to sunlight. A 2016 study pointed the finger at sulfates, which absorb in the UV spectrum, leading to degradation.
Even contemporary art materials are subject to irreversible color changes due to exposure to light and oxidizing agents, among other hazards. This is why recent work has been carried out on the use of nanomaterials for the conservation of works of art. Graphene has a number of properties that make it attractive for art conservation purposes. The one-atom-thick material is transparent, adheres easily to a variety of substrates, and provides an excellent barrier against oxygen, gases (corrosive or otherwise), and moisture. It is also hydrophobic and an excellent UV light absorber.
