example 1
[0025] In parts by weight, 100 parts of wood pulp with a solid content of 2%, 10 parts of sodium bromide, and 20 parts of oxidizing agent are successively poured into the reactor, and the pH is adjusted to 10.5 with a mass fraction of 8% sodium hydroxide solution. Then, at a temperature of 55°C and a rotation speed of 400r / min, the reaction was stirred at a constant temperature for 2 hours. After the reaction was completed, the materials in the reactor were transferred to a nano homogenizer, and homogenized three times at a pressure of 1800 bar to obtain nano fiber slurry, and the gained nanofiber slurry is filtered, washed and dried to obtain nanofibers; in parts by weight, 10 parts of nanofibers are successively taken, and 100 parts by mass fraction is 60% ethanol solution, and after mixing, the frequency is 40kHz Ultrasonic disperse for 20 minutes under the condition, and then add tetraethyl orthosilicate 1.2 times the mass of nanofibers to the ethanol solution under stirrin...

[0027] In parts by weight, 110 parts of wood pulp with a solid content of 4%, 11 parts of sodium bromide, and 25 parts of oxidizing agent are successively poured into the reactor, and the pH is adjusted to 10.8 with a mass fraction of 9% sodium hydroxide solution. Then, at a temperature of 58°C and a rotation speed of 500r / min, the reaction was stirred at a constant temperature for 3 hours. After the reaction was completed, the materials in the reactor were transferred to a nano homogenizer, and homogenized four times at a pressure of 1900 bar to obtain nano fiber slurry, and the gained nanofiber slurry is filtered, washed and dried to obtain nanofibers; in parts by weight, 15 parts of nanofibers are successively taken, and 110 parts of mass fraction are 70% ethanol solution, and after mixing, the frequency is 45kHz Ultrasonic disperse for 30 minutes under the condition, and then add tetraethyl orthosilicate 1.5 times the mass of nanofibers to the ethanol solution under stirrin...

[0029]In parts by weight, 120 parts of wood pulp with a solid content of 6%, 12 parts of sodium bromide, and 30 parts of oxidizing agent are successively poured into the reactor, and the pH is adjusted to 11.0 with a mass fraction of 10% sodium hydroxide solution. Then, at a temperature of 60°C and a rotation speed of 600r / min, the reaction was stirred at a constant temperature for 4 hours. After the reaction was completed, the materials in the reactor were transferred to a nano homogenizer, and homogenized for 5 times under a pressure of 2000 bar to obtain nano fiber slurry, and the gained nanofiber slurry is filtered, washed and dried to obtain nanofibers; in parts by weight, 20 parts of nanofibers are successively taken, and 120 parts of mass fraction are 80% ethanol solution, and after mixing, the frequency is 50kHz Ultrasonic disperse for 40min under the condition, then add tetraethyl orthosilicate which is 1.8 times the mass of nanofibers dropwise to the ethanol solution ...
