多孔碳基復合相變材料的可控合成、功能組裝與性能研究摘要

本文著重探討了多孔碳基復合相變材料的可控合成、功能組裝與性能研究，旨在為相變材料的可持續(xù)發(fā)展和實際應(yīng)用提供新思路和新思路。在介紹傳統(tǒng)相變材料的基本特性和優(yōu)缺點的基礎(chǔ)上，針對材料性能的缺陷和存在的問題，提出了多孔碳材料的合成方法和復合結(jié)構(gòu)方案。利用制備過程中的物理和化學方法，在納米結(jié)構(gòu)層面控制多孔結(jié)構(gòu)的大小、形狀、分布和密度，合成了具有空氣孔和介孔的多孔碳材料。然后利用這種多孔結(jié)構(gòu)，將相變材料納入其內(nèi)部，形成新型的多孔碳基復合相變材料。最后，測試了該材料的重要性能指標，如相變溫度、相變熱容、熱穩(wěn)定性和循環(huán)穩(wěn)定性等指標。研究結(jié)果揭示了多孔碳基復合相變材料的性能優(yōu)越性，更好地滿足了相變材料在能源存儲、傳輸和轉(zhuǎn)換等方面的需求，具有很高的實用價值和商業(yè)前景。
