Interview: „More efficient, durable and sustainable“ – Functional coatings contribute to a more sustainable future
How can modern coatings make buildings more energy-efficient, protect materials, and support environmental goals? Dr Diana Alves from the International Iberian Nanotechnology Laboratory explains how functionality and nanotechnology come together in smart coatings – and why they play a key role in driving sustainability forward.
What is the role of functional coatings in improving the energy efficiency of buildings and infrastructure?
Dr Diana Alves: The most basic form of coating that we can think of for buildings and infrastructure is paint, but it no longer serves only aesthetic purposes. Modern paints and coatings now offer multiple functionalities that enhance building performance. Superhydrophobic coatings, for example, prevent ice adhesion, corrosion and dirt accumulation on exterior buildings, extending the lifespan of materials and reducing maintenance costs. Hydrophilic coatings, especially the photocatalytic ones, push it a step further by breaking down contaminants under sunlight. Solar reduction coatings able to reflect sunlight can minimise solar heat gain while reducing the cooling energy. Additionally, phase-change material coatings help regulate the interior temperatures by absorbing excess heat before it enters the buildings. Therefore, functional coatings make buildings more efficient, durable and sustainable.

How do functional coatings with UV protection or photosensitive properties impact the sustainability efforts of different industries?
Alves: Functional coatings with UV protection or photosensitive properties play a crucial role in increasing sustainability across various industries by extending the lifespan of materials and reducing maintenance needs. One of the biggest challenges for both traditional and advanced functional materials used in high-UV environments or outdoors is light-induced damage, which significantly shortens their operational durability. UV-protective coatings help mitigate this issue by shielding materials from harmful radiation, preventing degradation, and reducing the need for frequent replacements or repairs. In industries such as construction, automotive, and textiles, UV-resistant coatings improve energy efficiency by preserving surface integrity and preventing discoloration or material breakdown.
How is nanotechnology contributing to the development of smart coatings with enhanced properties?
Alves: Nanotechnology is a game-changer in the development of smart coatings, offering groundbreaking innovations that boost efficiency, durability, and sustainability. By manipulating materials at the nanoscale, researchers have unlocked new properties that improve coatings with self-cleaning, UV protection, corrosion resistance, and antimicrobial effects. These advancements are transforming industries such as construction, healthcare, and environmental protection by extending material lifespan, reducing maintenance, and increasing energy efficiency. Nanotechnology-driven smart coatings play a vital role in resource management and environmental conservation, contributing to a more sustainable future.
