Novel sustainable polymer-based phase change materials (PCMs) for mortars based...
Sarcinella, Antonella; Aguiar, J. L. Barroso de; Cunha, Sandra Raquel Leite; Frigione, MariaenricaA possible solution to reduce the consumption of fossil fuel and energy demand to power heating and cooling devices is represented by Phase Change Materials (PCMs). They can absorb, store and release energy according to their physical state that changes with the environmental temperature. In this work, novel eco-sustainable PCMs were developed through the form-stable method. Through this process, it was possibl...

Sarcinella, Antonella; Cunha, Sandra Raquel Leite; Aguiar, Ingried; Aguiar, J. L. Barroso de; Frigione, MariaenricaThe growing demand for sustainable energy solutions has intensified research on phase change materials (PCMs) due to their ability to efficiently store and release thermal energy. However, traditional PCMs are often made from petroleum-derived materials or rely on processes that pose environmental concerns. The aim of this work is therefore to explore the development and use of sustainable organic PCMs, in part...

Sarcinella, Antonella; Cunha, Sandra Raquel Leite; Reis, Nuno; Aguiar, J. L. Barroso de; Frigione, MariaenricaThe development of construction materials with the integration of phase change materials (PCMs) has been a topic of wide interest in the scientific community, especially in recent years, due to its positive impact on temperature regulation inside buildings. However, little is known about the behavior of materials doped with PCMs when exposed to accidental or severe environments. Currently, a large area of the p...

Cunha, Sandra Raquel Leite; Sarcinella, Antonella; Reis, Nuno; Aguiar, J. L. Barroso de; Frigione, MariaenricaThe integration of a phase change material in mortar promises to improve thermal comfort and reduce energy consumption. Assessing mortar behavior under diverse temperature conditions, especially high ones encountered in unforeseen disasters or accidents, is essential for evaluating their reliability and resilience in safeguarding building safety and longevity. This research examines the behavior of cement-based...

Sarcinella, Antonella; Cunha, Sandra Raquel Leite; Aguiar, J. L. Barroso de; Frigione, MariaenricaPhase Change Materials (PCMs) in building materials can significantly reduce energy consumption in heating and cooling systems. PCMs absorb, store, and release thermal energy by transitioning between solid and liquid states based on external temperatures, helping to regulate indoor temperatures and lower energy use. This study evaluates the thermal performance of various mortar compositions containing PCMs made...

Sarcinella, Antonella; Cunha, Sandra Raquel Leite; Aguiar, J. L. Barroso de; Frigione, MariaenricaThe high global energy demand drives the search for sustainable alternatives for energy production and storage. Among the most effective solutions are phase change materials (PCMs). In particular, organic PCMs offer a high capacity to store and release thermal energy in response to external thermal variations, even over a wide temperature range. They find profitable applications in various sectors, from constru...

Cunha, Sandra Raquel Leite; Sarcinella, Antonella; Aguiar, J. L. Barroso de; Frigione, MariaenricaThe construction industry is responsible for high energetic consumption, especially associated with buildings’ heating and cooling needs. This issue has attracted the attention of the scientific community, governments and authorities from all over the world, especially in the European Union, motivated by recent international conflicts which forced the countries to rethink their energy policies. Over the years, ...

Sarcinella, Antonella; Aguiar, J. L. Barroso de; Cunha, Sandra Raquel Leite; Frigione, MariaenricaThe buildings sector is one of the main contributors to the use and consumption of fossil fuel energy and, consequently, to the CO2 emissions. This evidence is more widespread in industrialized countries where energy is used for heating and cooling purposes. This trend is not destined to change since climate change affects temperatures making them hotter in summer and colder in winter. A solution to this issue ...

Sarcinella, Antonella; Aguiar, J. L. Barroso de; Jesus, Carlos Manuel Gonçalves; Frigione, MariaenricaThe purpose of a phase change material (PCM) is to store/release energy during its transition from solid to liquid state, being able to count on a range of melting/crystallization temperatures comparable to environmental temperatures. The inclusion of a PCM in mortars, or in other construction elements, guarantees a reduction in energy consumption for heating and cooling of buildings, provided that the phase tr...
