Abstract Phase change materials (PCMs) possess remarkable capability to store and release substantial amounts of energy during the processes melting crystallization across a wide temperature range, thus holding great promise in applications related regulation thermal storage. Herein, effectively address PCM leakage enhance conduction, microcapsules with melamine–formaldehyde resin (MF) shell were prepared using situ polymerization Pickering emulsions stabilized by cellulose nanofibrils (CNFs). CNFs selected as stabilizers for reinforcing nanofillers MF shell, owing their excellent emulsifying capability, high mechanical strength, sustainable nature. Paraffin wax (PW) was utilized material. The resulting shells PW core had diameter ranging from 2 4 µm. Results showed that microcapsule core–shell ratio (Micro-2.0) exhibited highest latent heat fusion, measuring approximately 128.40 J/g 120.23 J/g, respectively. encapsulation efficiency Micro-2.0 determined be 79.84%.

MXene Hollow Spheres Supported by a C–Co Exoskeleton Grow MWCNTs for Efficient Microwave Absorption

Nano-Micro Letters, Год журнала: 2024, Номер 16(1)

Опубликована: Фев. 2, 2024

High-performance microwave absorption (MA) materials must be studied immediately since electromagnetic pollution has become a problem that cannot disregarded. A straightforward composite material, comprising hollow MXene spheres loaded with C-Co frameworks, was prepared to develop multiwalled carbon nanotubes (MWCNTs). high impedance and suitable morphology were guaranteed by the exoskeleton, attenuation ability provided MWCNTs endoskeleton, material performance greatly enhanced layered core-shell structure. When thickness only 2.04 mm, effective bandwidth 5.67 GHz, minimum reflection loss (RL

Compared with traditional injection foaming, co-injection foaming serves as a method to prepare products high-quality surfaces and enhanced mechanical properties, demonstrating excellent technical advantages economic benefits. The effects of high-density polyethylene (HDPE) content, agent melting temperature core material, nano-organic montmorillonite (OMMT) content on the cell structure, crystallization behavior isotactic polypropylene (iPP)/HDPE composite foam prepared by were systematically studied. At 2 wt.%, HDPE 30 OMMT 3 material 190 °C, exhibited size measuring 85 μm, density 2.5 × 105 cells/cm3, tensile strength 25.8 MPa, an impact 12.5 kJ/m2. addition reduced crystallinity iPP matrix, while enhancing solubility carbon dioxide within matrix. non-miscible interface between helped reduce energy barrier for nucleation. Furthermore, introduction nucleating in iPP/HDPE dramatically decreased These synergistic result smaller higher density, exhibiting comprehensive properties. This work provides feasible preparing performance.
