Покрытие-хамелеон эффективно охладит или согреет дома, изменяя свой цвет

Международная группа исследователей под руководством профессора Харбинского технологического института Фуцяна Вана завершила эксперимент по изучению материала-хамелеона. Им потребовалось более 12 месяцев, чтобы оценить его работу в разные времена года. Эксперимент признан успешным – новое покрытие в пассивном режиме может и охлаждать, и согревать здания.

Идею ученые подсмотрели у хамелеона Намаквы, уроженца пустынь юго-западной Африки. От природы он имеет темно-коричневый окрас, что помогает коже поглощать тепло, но по мере роста температуры окружающего воздуха цвет рептилии меняется на светло-серый. Поглощение тепла радикально снижается, что позволяет пережить значительный суточный перепад температур в пустыне.

Новый материал получил название «температурно-адаптивное охлаждающее покрытие». Он состоит из микрокапсул с поливинилиденфторидом — веществом, которое меняет цвет и способность поглощать инфракрасное излучение в зависимости от своей температуры. Процесс запускается при температуре в 20 ºC — темно-серый цвет меняется на светло-серый. При достижении 30 ºC вещество становится настолько светлым, что отражает 93 % солнечных лучей.

В ходе годового эксперимента новинка показала наилучшие результаты по пассивному охлаждению зданий в сравнении с белой краской и различными видами черепицы. Еще лучшие показатели достигаются при наступлении погоды, во время которой суточная разница в температуре становится наиболее выраженной. Увы, о практическом применении нового материала пока речи не идет, он все еще остается на стадии исследования.
