Nanocellulose has extremely low density, but also has excellent mechanical strength. It can be combined with other materials to make lightweight composite materials and is used in spacecraft structures. These composite materials are not only light, but also provide sufficient structural support, suitable for use in spacecraft fuselages, wings and other components. 2. Thermal protection materials The spacecraft experiences extremely high temperatures when entering or returning to the atmosphere, and requires highly heat-resistant materials to protect the spacecraft. Nanocellulose has good heat resistance and can be used as a heat insulation material after modification to help reduce

As a new material, nanocellulose has excellent mechanical properties and environmental protection characteristics and is gradually being used in the production of plywood.

It can form a good combination with adhesives and wood fibers, enhance the adhesion of plywood and interlayer bonding strength, thereby reducing the plywood during use. stratification phenomenon. 3. Environmental protection performance: Compared with traditional chemical reinforcers, nanocellulose is a natural material that is harmless to the environment. Using nanocellulose in plywood production can reduce the

Nanocellulose and microcrystalline cellulose (MCC) are both derived from natural cellulose, but they are significantly different in structure, preparation method, physical and chemical properties and application fields. The following are the main differences between them: 1. Definition and structure 1. Nanocellulose (Nanocellulose) o Definition: Nanocellulose refers to nano-scale materials composed of cellulose molecules, usually including cellulose nanofiber filaments (CNF) and cellulose nanocrystals (CNC). Its size is generally at the nanometer level, its diameter is usually between a few nanometers and tens of nanometers, and its length can reach several microns or even longer. o Structure: Nanocellulose can be manifested as long fibrous (CNF) or short rod (CNC), with a highly dispersed fibrous structure. It has a higher specific surface

Bacterial Cellulose (BC) is a cellulose material synthesized by bacteria. It has high purity, high crystallinity, high mechanical strength and other characteristics. It is widely used in biomedicine, food, environmental protection and other fields. The following is the preparation process of bacterial cellulose: 1. The preparation process of bacterial cellulose 1. Select bacterial strains to prepare bacterial cellulose The most commonly used strain is Gluconacetobacter xylinus of the genus genus Gluconacetobacter xylinus, because it can be synthesized efficiently. Cellulose. In addition, other bacterial species with cellulose-producing ability can also be used to prepare bacterial cellulose. 2.

The following are the main differences between them: 1. Structure and morphology 1. Cellulose nanofiber filaments (CNF) o Structure: Cellulose nanofiber filaments are long fibrous nanomaterials composed of cellulose molecular chains. Its structure is usually relatively flexible and long, showing a higher aspect ratio (the ratio of length to diameter). o Morphology: CNF usually exists in fibrous shape, with a diameter ranging from several nanometers to tens of nanometers, and a length of up to several micrometers to tens of micrometers. 2. Cellulose nanocrystals (CNC) o Structure: Cellulose nanocrystals are cellulose nanocrystals obtained by acid hydrolysis, with a more structure

The application of nanocellulose in the petroleum field is gradually attracting attention, mainly because it has the advantages of high strength, low density, good adsorption and biodegradability. The following are some potential applications of nanocellulose in the petroleum industry: 1. Oil well drilling fluid Drilling fluid is a very important material in the oil mining process, and plays a role in cooling, lubrication of drill bits and carrying drill chips. Nanocellulose can be used as an environmentally friendly additive to improve the rheology performance and filtration loss control effect of drilling fluid. Compared with traditional synthetic polymers, nanocellulose has better environmental protection and degradability, which can reduce the impact of drilling fluid on the environment and improve the efficiency of downhole operation. 2. Oil-water separation In the oil-water mixture is a common by-product during oil extraction and production. Nanocellulose can be used to develop efficient oil-water separation materials. Due to its high surface area and good adsorption properties, this type of material can effectively adsorb oil droplets and transfer them to

To make acrylic acid (especially polyacrylic acid) and nanocellulose compatible in composite materials, the following strategies can improve the compatibility of the two: 1. Chemical modification: • Surface modified nanocellulose: by surface modification (such as carboxylation, sulfonation or grafting polymers) to enhance the interaction of nanocellulose with acrylic acid. For example, carboxylated nanocellulose can interact with the carboxyl groups in acrylic acid through hydrogen bonds, thereby improving the mechanical strength and stability of the composite material. • Graft copolymerization: Graft copolymerization can be performed by introducing other monomers, such as methacrylate, to enable better cross-linking of acrylic segments and nanocellulose. 2. Use of crosslinking agents: • The use of crosslinking agents (such as N,N'-methylenebisacrylamide) can form chemical bonds between acrylic acid and nanocellulose, thereby improving the mechanical properties and water absorption capacity of the composite material. This crosslinking method is often used to prepare super-water absorbent materials. 3.

Nanofibers and nanocellulose are two materials with nanoscale characteristics, and they differ significantly in composition, structure and application fields. Here are their main differences: 1. Composition materials: o Nanofibers: Nanofibers are fibers made of a variety of materials with diameters in the nanoscale (1 nanometer to several hundred nanometers). These materials can be synthetic (such as polymer nanofibers, carbon nanofibers) or natural (such as silk protein nanofibers). The composition of nanofibers is very wide, and the appropriate materials can be selected according to the application needs. o Nanocellulose: Nanocellulose is a nanoscale material made of natural cellulose. Cellulose is the main component of plant cell walls, so nanocellulose is usually derived from plant materials such as wood, bamboo, and cotton. Nanocellulose can be divided into two categories according to its structure: nanowhisker cellulose (CNC) and nanofiber cellulose (CNF). 2. Structure and
