“…Fluoropolymers are often used in conjunction with other polymer types to realize these properties; however, with the USA and EU proposing further restricting fluorocarbon-containing substances, their widespread use in coatings will need to be replaced. 32 The carrier solvent used in coatings is another major concern, with some recent research focusing on the development of waterborne [33][34][35][36][37][38][39] or solventless 40,41 systems for lower environmental impact. Restrictions on volatile organic compounds have helped facilitate this push to reduce the overall environmental impact and toxicity of common coating solvents including hydrocarbons, ketones, esters, and alcohols which can have harmful effects on the user and other organisms if exposed through contact or inhalation.…”

Mankind has erected monoliths and stone structures for millennia to ensure stories and culture are passed on to future generations. In the modern era, monuments and architecture are designed with the intention of lasting several decades to hundreds of years and may utilize an arrangement of natural and synthetic materials. Choice of substrate helps ensure the longevity of these structures, but coatings are utilized to provide additional characteristics and subsequent protection to the finished product. Protective coatings come in a variety of base materials and are utilized to address specific degradation concerns of the project managers. Advances in this field focus on protection of the surface while preventing any unintended damage to the substrate. This mini‐review summarizes the advances in protective coatings useful for historical monuments and architecture up to January 2024.This article is protected by copyright. All rights reserved.

The industrial application of UV curable coatings is being widely commercialized at a rapid pace with very diversified product markets. UV curing has existed for many years now, but the new commercial opportunities emerging for sustainable, and climate friendly technologies have driven demand for photo-curable coating systems. It is primarily attributed to its environmentally friendly solvent-free and energy-efficient method. Precedented UV light curable coatings are being commercialized and numerous lamp sources are being extensively studied. In such an era of predominant research evolving the UV curing technology horizon, we attempt to outline the state of the art, opportunities, and challenges. This contribution attempts to highlight, in a comprehensive way, sustainable UV coating on the basis of recent research advancements, existing challenges and prospective scope in this field. With a set of prerequisite foundational knowledge into UV curable coatings and mechanisms, the review has meticulously looked at the recent research advancements. This review contribution attempts to focus on three aspects: the known science behind UV curing coatings, coupled with the recent advancements, and future opportunities.

The development of photocurable compositions is in high demand for the manufacture of func-tional materials for electronics, optics, medicine, energy, etc. The properties of the final pho-to-cured material are primarily determined by the initial mixture, which needs to be tuned for each application. In this study we propose to use simple systems based on di(meth)acrylate, polyimide and photoinitiator for the preparation of new photo-curable compositions. It was es-tablished that a fluorinated cardo copolymide (FCPI) based on 2,2-bis-(3,4-dicarboxydiphenyl)hexafluoropropane dianhydride, 9,9-bis-(4-aminophenyl)fluorene and 2,2-bis-(4-aminophenyl)hexafluoropropane (1.00:0.75:0.25 mol) has excellent solubility in di(met)acrylates. This made it possible to prepare solutions of FCPI in such monomers, to study the effect of FCPI on the kinetics of their photopolymerization in situ and the properties of the resulting polymers. According to the obtained data, the solutions of FCPI (23 wt.%) in 1,4-butanediol diacrylate (BDDA) and FCPI (15 wt.%) in tetraethylene glycol diacrylate were tested for the formation of the primary protective coatings of the silica optical fibers. It was found that the new coating of poly(BDDA–FCPI23%) can withstand prolonged annealing at 200°C (72 h), which is comparable or superior to the known most thermally stable photo-curable coatings. The proposed approach can be applied to obtain other functional materials.
