Resumen
Este estudio introduce un tejido adaptativo al medio ambiente (EAF) para la gestión térmica personal sostenible (PTM). El nuevo tejido proporciona un enfriamiento radiativo eficiente en diversas condiciones y demuestra una excelente durabilidad para aplicaciones cotidianas de prendas de vestir.
Área de la Ciencia:
- Ciencias de los materiales
- Nanotecnología
- Ingeniería textil
Sus antecedentes:
- Los textiles de refrigeración radiativa ofrecen una gestión térmica personal sostenible (PTM) al emitir calor corporal al espacio y reflejar la luz solar.
- Los tejidos PTM existentes carecen de adaptabilidad ambiental y a menudo se prueban en entornos de aplicación única.
- Se necesitan tejidos refrescantes robustos y adaptables adecuados para el uso diario.
Objetivo del estudio:
- Desarrollar un tejido adaptativo al medio ambiente (EAF) para un enfriamiento radiativo eficiente.
- Investigar el rendimiento del tejido en diversas condiciones ambientales y tratamientos.
- Demostrar el potencial de EAF para los textiles de gestión térmica inteligente de próxima generación.
Principales métodos:
- Fabricación de EAF utilizando poliformaldehído (POM) y SiO2 hueco basado en la teoría de la dispersión de Mie y el diseño de la micronanostructura.
- Caracterización de las propiedades ópticas, incluida la emisión selectiva en la ventana atmosférica (8-13 μm), la transmisión (2,5-25 μm) y la reflexión de la luz solar (0,3-2,5 μm).
- Prueba de la durabilidad de las propiedades ópticas bajo tratamientos ácidos, alcalinos y UV.
Principales resultados:
- El EAF exhibe una alta selectividad óptica, lo que permite un enfriamiento radiativo eficiente.
- El tejido mantiene excelentes propiedades ópticas después de la exposición a tratamientos ambientales adversos (ácido, alcalino, UV).
- Se ha demostrado un efecto de enfriamiento significativo (1,5-12,2 °C por debajo de los tejidos de control) tanto en ambientes exteriores como interiores.
Conclusiones:
- El EAF desarrollado muestra una excelente adaptabilidad al medio ambiente y robustez, adecuado para el uso diario de prendas de vestir.
- Este trabajo presenta una nueva vía para el diseño de textiles avanzados y sostenibles de gestión térmica inteligente.
- La tecnología EAF es prometedora para aplicaciones más amplias en soluciones sostenibles de gestión térmica.

Consider an external electric field propagating through a homogeneous medium. When the electric field crosses the surface boundary of the medium, it undergoes a discontinuity. The electric field can be resolved into normal and tangential components. The amount by which the field changes at any boundary is given by the difference between the field components above and below the surface boundary.
The surface integral of an electric field is given by Gauss's law in integral form and is related to...

Understanding heat transfer mechanisms is essential for understanding how our bodies maintain balance in different environmental conditions. When the environment is thermoneutral, the body is in a state of balance, neither using nor releasing energy to maintain its core temperature. However, when the environment is not thermoneutral, the body employs four heat transfer mechanisms to maintain homeostasis: conduction, convection, evaporation, and radiation. These mechanisms facilitate heat...

01:27Electrostatic Boundary Conditions in Dielectrics
1.4K
When an electric field passes from one homogeneous medium to another, crossing the boundary between the two mediums imparts a discontinuity in the electric field. This results in electrostatic boundary conditions that depend on the type of mediums the field propagates through.
Consider a case where both the mediums across a boundary are two different dielectric materials. Recall that the electric field and electric displacement are proportional and related through the material's...

Heat transfer between the human body and its environment occurs through four main mechanisms: conduction, convection, radiation, and evaporation.
Conduction, accounting for approximately 3% of body heat loss at rest, is the process of exchanging heat between molecules of two materials in direct contact. This can result in both heat loss and gain. For instance, when the body is submerged in water, which conducts heat 20 times more effectively than air, it can either lose or gain significant...

In convection, thermal energy is carried by the large-scale flow of matter. Ocean currents and large-scale atmospheric circulation, which result from the buoyancy of warm air and water, transfer hot air from the tropics toward the poles and cold air from the poles toward the tropics. The Earth’s rotation interacts with those flows, causing the observed eastward flow of air in the temperate zones. Convection dominates heat transfer by air, and the amount of available space for the airflow...

1.2K
The average temperature of Earth is the subject of much current discussion. Earth is in radiative contact with both the Sun and dark space; it receives almost all its energy from the radiation of the Sun and reflects some of it into outer space. Dark space is very cold, about 3 K, so Earth radiates energy into it. For instance, heat transfer occurs from soil and grasses, the rate of which can be so rapid that frost can occur on clear summer evenings, even in warm latitudes.
