Flexible thermal conductive Al₂O₃@siloxane composite with rapid self-healing property based on carboxyl-amine dynamic reversible bonds

Abstract

Thermal interface materials (TIMs) are one of the efficacious ways to alleviate the heat accumulation problem of microelectronics devices.

Covalently Functionalized Leakage‐Free Healable Phase‐Change Interface Materials with Extraordinary High‐Thermal Conductivity and Low‐Thermal Resistance

“…b) Tensile strength of the pristine and healed OP‐Ag‐nAgMWNT as a function of healing temperature. c) Tensile strength and healing efficiency of the OP‐Ag‐nAgMWNT (red star) are compared with those of healable TIMs in the literature (black open square, [ 66 ] gray open circle, [ 67 ] blue open triangle, [ 68 ] magenta inverted open triangle, [ 69 ] olive open diamond, [ 70 ] navy left pointed open triangle, [ 71 ] violet right pointed open triangle, [ 72 ] purple open hexagon, [ 73 ] and wine open pentagon [ 74 ] ). d,e) Thermal conductivity and total thermal resistance of the pristine and healed OP‐Ag‐nAgMWNT as a function of healing temperature.…”

Prestrain Programmable 4D Printing of Nanoceramic Composites with Bioinspired Microstructure

“…The strength, modulus, and inorganics content of various flexible, printable inorganic composites in this work and from the literature (Table S1, Supporting Information) were summarized in Figure 3t,u. [ 33–59 ] FANC displayed the best mechanical performances in the flexible printable inorganic composites. Typically, ceramic‐based materials cannot realize flexibility, and polymer‐based materials do not possess sufficient stiffness to satisfy the shape retention during 4D printing.…”

“…A comparison of t) tensile strength and u) modulus versus inorganics content between FANC and the printable flexible inorganic composites from the literature. [ 33–59 ] The details of these studies are listed in Table S1, Supporting Information. The microstructures of the struts printed through a v) star nozzle, w) rectangle nozzle, and x) square nozzle, respectively.…”
