AI Technical Summary

Benefits of technology

The invention is a nanosized composite material made up of a nanocellulose core and a metal shell. This composite material has high mechanical strength. The size of the material is controlled within the nano range, which reduces blocking issues. The nanocellulose core has high crystallinity, which increases the overall mechanical strength of the composite material. The nanocellulose core also acts as a supportive template to prevent metal melting from affecting electrical properties. The manufacturing process of this composite material is simpler because the metal shell is defined by the nanocellulose core, and there is no need to remove the nanocellulose core.

Problems solved by technology

If the metal material is too big, then the issue of nozzle blockage may occur in the printing process.
Therefore, the process steps are more complex.
Moreover, the one-dimensional structure of the known techniques often melts and breaks into fragments or melts into particles due to increased temperature such that the original form is lost.

Embodiment Construction

[0033]FIG. 1 is a schematic of a composite material shown according to some embodiments of the invention.

[0034]Referring to FIG. 1, a composite material 100 of the present embodiment includes a nanocellulose core 110 and a metal shell 120. The metal shell 120 covers a surface of the nanocellulose core 110.

[0035]

[0036]The material of the nanocellulose core 110 includes, for instance, plant-based, algae-based, or bacteria-based cellulose nanofibril (CNF), cellulose nanocrystal (CNC), bacterial cellulose (BC), or a combination thereof. In some embodiments, the material of the nanocellulose core 110 is, for instance, crystalline cellulose. In some embodiments, the weight average molecular weight of the nanocellulose core 110 is, for instance, between 500 and 500000. In some embodiments, the diameter of the nanocellulose core 110 is, for instance, between 2 nanometers and 200 nanometers. In some other embodiments, the diameter of the nanocellulose core 110 is, for instance, less than 5 n...
