Biyokömürler, yüksek yüzey alanı ve gözenekli yapıları sayesinde, FDM/biyokömür kompozitleri için etkili bir taban malzemesi olarak değerlendirilebilirler. Bu şekilde üretilen şekil kararlı FDM/biyokömür kompozitleri, enerji depolama ve termal koruma gibi farklı uygulamalarda kullanılma potansiyeline sahiptirler. Piroliz yoluyla üretilen biyokömürlerin maksimum yüzey alanı, gözenek boyutları ve dağılımları; maksimum piroliz sıcaklığı, ısıtma hızı ve bekletme süresi gibi parametrelere göre değişmektedir. Bu çalışmada maksimum piroliz sıcaklığının biyokömür gözenekliliği üzerindeki etkileri, gözenekler içerisine emdirilen FDM miktarı açısından değerlendirilmiştir. Bu amaçla doğadan elde edilen kavak talaşından, farklı piroliz maksimum sıcaklıkları kullanılarak biyokömürler elde edilmiştir. Elde edilen biyokömür gözeneklerine vakum emdirme yöntemiyle FDM emdirilerek Biyokömür/FDM kompozitleri oluşturulmuştur. Biyokömür/FDM kompozitlerinin ısı depolama kapasiteleri Diferansiyel Taramalı Kalorimetre ile belirlenmiştir. Elde edilen bulgular, piroliz maksimum sıcaklığının düşmesi ile Biyokömür/FDM kompozitlerinin enerji depolama kapasitelerinin arttığını göstermiştir.

Biochars can be considered as effective base materials for PCM/biochar composites due to their high surface area and porous structures. Shape-stable PCM/biochar composites produced in this way have the potential to be used in various applications such as energy storage and thermal protection. The maximum surface area, pore sizes, and distributions of biochars produced through pyrolysis vary according to parameters such as maximum pyrolysis temperature, heating rate, and holding time. In this study, the effects of maximum pyrolysis temperature on biochar porosity were evaluated in terms of the amount of PCM impregnated into the pores. For this purpose, biochars were obtained from naturally sourced poplar sawdust using different pyrolysis maximum temperatures. Biochar/PCM composites were created by impregnating PCM into the biochar pores using the vacuum impregnation method. The heat storage capacities of Biochar/PCM composites were determined by Differential Scanning Calorimetry. The results showed that as the pyrolysis maximum temperature decreased, the energy storage capacities of Biochar/PCM composites increased.
