PROJECT PN-II-RU-TE-2014-4-1587

Project financed by UEFISCDI, Executive Agency for Higher Education, Research, Development and Innovation Funding Human Resources PROGRAMME, Research projects for the stimulation of the funding of young independent research teams (TE)
Host institution: Politehnica University of Timişoara
Project code: PN-II-RU-TE-2014-4-1587
Project registration number: 142/01.10.2015
Project title: Combustion synthesis of smart near-infrared reflective nanopigments for heat reflective (cool) coatings
Acronym: NANOTHERMOREFLECT

About the project

Under the action of solar radiation, of which 54 % is represented by the Near Infrared (NIR) thermal radiation, the roof and facade temperature increases excessively causing less thermal comfort and a massive increase in the electricity needed for air conditioning cooling. An efficient approach for overcoming the negative effect of excessive heating due to solar radiation is the use of smart thermo-reflecting inorganic pigments, which selectively absorb the radiation in the visible range generating the desired color and at the same time reflect the NIR radiation responsible for overheating. In order to decrease the high pigment cost caused by the manufacturing process, which is time and energy consuming, this project suggests for the first time the preparation of some smart NIR reflective nanopigments using an eco-friendly, faster and energy efficient synthesis method known as combustion synthesis. In this new approach, ZnAl₂O₄ and LaAlO₃ doped with transition metal ions nanopigments with a broad color range (white, green, blue, brown, black) answering the market demands are obtained in a matter of seconds directly from the exothermic combustion reaction, without any annealing stage – which allows significant cuts in the production costs. The key properties of these smart NIR reflective pigments (color, thermo-reflectivity, particle size) are assessed in various cool paint and coating recipes, suitable for concrete, ceramic and metallic roofs.
