Article Synopsis
- - The study explores the use of sunflower biomass (stems and receptacles) mixed with polyethylene glycol to create shape-stabilized phase change materials, aiming to boost energy efficiency due to their high thermal conductivity and storage capability.
- - Sunflower stem carbon (SS-PEG) and receptacle carbon (SR-PEG) were synthesized using a vacuum impregnation method, and their structural and thermal properties were analyzed with various techniques like SEM and DSC.
- - Results indicated that SS-PEG and SR-PEG have significant melting enthalpies of 153.4 J/g and 171.5 J/g, respectively, achieving high loading rates of 81.9% and 91.5%, while also exhibiting good thermal stability with
To alleviate the increasing energy crisis and achieve energy saving and consumption reduction in building materials, preparing shape-stabilized phase-change materials using bio-porous carbon materials from renewable organic waste to building envelope materials is an effective strategy. In this work, pine cone porous biomass carbon (PCC) was prepared via a chemical activation method using renewable biomaterial pine cone as a precursor and potassium hydroxide (KOH) as an activator. Polyethylene glycol (PEG) and octadecane (OD) were loaded into PCC using the vacuum impregnation method to prepare polyethylene glycol/pine cone porous biomass carbon (PEG/PCC) and octadecane/pine cone porous biomass carbon (OD/PCC) shape-stabilized phase-change materials.
