Embodiment 1

[0042] Embodiment 1. Utilize corn stover to prepare nanocellulose (nanocellulose)

[0043] Corn stalks consist of a hard rind (husk) on the outside and a pith (core) on the inside.

[0044] Rind and pith are composed of different tissues. Before using corn stalks to prepare nanocellulose, the Rind and Pith of corn stalks were separated. figure 1 Show the separated corn stalk Rind and Pith, the optical microscope photos of Rind and Pith are as figure 2 shown.

[0045] In order to prepare nanocellulose using the separated Rind and Pith of corn stalks, a lignin removal step was first performed. The lignin removal process can be removed through a pulping process and a bleaching process.

[0046] In the present invention, lignin (lignin) is removed by the following bleaching process, and the specific process is as follows.

[0047] After adding 1000 mL of distilled water to rind and pith of 30 g of oven dry corn stalks, 15.5 g of NaClO2 and 1.0 mL of acetic acid were added, a...

Embodiment 2

[0050] Embodiment 2. Utilize oil palm trunk (oil palm trunk) to prepare nanocellulose (nanocellulose)

[0051] (1) Oil palm trunk fibers are composed of vascular bundles and parenchyma cells at a ratio of 50:50. Although the vascular bundles are linear and elongated similar to other woody fibers, the parenchyma cells are short and round. Therefore, when oil palm trunks are made into pulp for papermaking, inter-fiber bonding is disturbed due to parenchyma cells, so the parenchyma cells are separated before or after pulping.

[0052] The separation of parenchyma cells before pulping can be carried out by using the density difference between parenchyma cells and vascular bundles, and the separation of parenchyma cells after pulping can be carried out by Bauer Mcnett et al. After pulping, the process of using Bauer Mcnett to separate parenchyma cells is as follows. Each part uses 28, 48, 100, and 200 mesh steel wire mesh to separate long rod-shaped vascular bundles and short roun...

experiment example 1

[0068] Experimental Example 1. Confirmation of nanocellulose (nanocellulose) prepared from corn stalks

[0069] According to Example 1, the nanocellulose prepared from the rind and pith of corn stalks was confirmed by TEM analysis. TEM imaging conditions were diluted to 0.001%, put on a grid, and stained with uranyl acetate. Shooting was carried out under the condition of accelerating voltage 120KW.

[0070] The result is as Figure 10 As shown, it was confirmed that the prepared nanocellulose showed a difference in shape depending on rind and pith, and the nanocellulose prepared by rind showed a linear rod shape similar to nanocellulose of wood-derived fibers. However, it was confirmed that the nanocellulose made of pith is not in the shape of a linear rod, but in the shape of a sphere. This was judged to be due to the production of spherical nanocellulose due to parenchyma cells in the pith of corn stalks.

Abstract

The present invention relates to: nanocellulose to be prepared by using non-lignocellulosic biomass; and a cosmetic composition, a superabsorbent material and the like, which utilize the nanocellulose. According to the present invention, nanocellulose is prepared by using biomass, which has been treated as waste, and a cosmetic composition and the like are prepared by utilizing the same, and thus the present invention has an effect of enabling a new added value to be created.

Description

technical field [0001] The present invention relates to nanocellulose, and more specifically, to a nanocellulose prepared from non-woody biomass (biomass), a cosmetic composition, a superabsorbent material, and the like using the nanocellulose . Background technique [0002] Cellulose is widely used in paper products such as printing paper, magazines, newspapers, boxes, and toilet paper, cosmetic paper, paper towels, baby diapers, adult diapers, feminine sanitary napkins, etc. as disposable hygiene products. [0003] As of now, as a raw material of cellulose for producing the above products, trees are almost mostly used. However, recently, as part of environmental protection measures and measures to prevent global warming, under the leadership of the United States, Canada, and northern European developed countries, efforts are being made to develop cellulose instead of trees using non-wood (Non-Wood) plants as raw materials. Research. [0004] As representative examples t...
