Abstract A promising new form-stable phase change material (PA/PB) was fabricated using pinecone biochar (PB) as the supporting of palmitic acid (PA). The PB with large surface area produced by forest residue pinecone, and it cheap, environment friendly easy to prepare. firstly utilized supporter PA characterizations PA/PB were analyzed BET, SEM, XRD, DSC, TGA, FT-IR thermal conductivity tester. results demonstrated that physically absorbed crystal structure not destroyed. DSC showed fusing...

Recently, the recovery and reuse of natural fibers have gained much attention. However, kapok fiber as a kind cellulose is difficult to recycle because its poor mechanical property. In this study, facile, universal, brand new strategy was proposed by taking partial dissolution self-assembled regeneration for fabricating regenerated (R-KFs). The R-KFs exhibit compact structure, structural densification obtained in process make possess high strength. Then, tensile strength enhanced 37 times...

Superhydrophobic sponges have considerable potential for oil/water separation. Most of the methods used superhydrophobic modification require toxic or harmful solvents, which drawbacks hazardous to environment, expensive, and complex utilize. Moreover, hydrophobic layer on surface sponge is often easily destroyed. In this paper, a highly efficient with excellent reusability was developed by using facile, simple environmentally friendly dopamine biomimetic bonding method. Different types...
