ncc‑g‑ech method to enhance EP performance

[0022] Example 1:

[0023] A method for NCC-g-ECH to enhance EP performance. The method includes the following steps:

[0024] (1) Alkalization of nanocellulose;

[0025] (2) Nano-cellulose grafted with epichlorohydrin;

[0026] (3) Blend the product after grafting into epoxy resin;

[0027] (4) Curing the blended epoxy resin.

[0028] Example 2:

[0029] According to the method of NCC-g-ECH to enhance EP performance as described in Example 1, the alkalization of nanocellulose: Take 1g of nanocellulose and pour into a three-necked flask, add 15ml of 95% ethanol-water solution, and add 15ml of 2%. The NaOH-aqueous solution was stirred at 65℃ for 1 h;

[0030] Example 3:

[0031] According to the method of NCC-g-ECH to enhance EP performance described in Example 1 or 2, the nanocellulose grafted with epichlorohydrin was injected into a three-necked flask with 2 ml of epichlorohydrin, and the mixture was stirred for 2 hours to prepare 70 % Isopropanol-water solution, repeatedly wash the grafted nanocellulose with the prepared isopropanol solution, and pour the washed white precipitate into a clean small beaker to dry;
