Green bio-based new materials for the dual-carbon era

Nanocellulose ( NC ) is a biomass nanomaterial prepared from natural plant fibers through green pretreatment and nanodissociation processes. It mainly includes three categories: cellulose nanofibrils ( CNF ) , cellulose nanocrystals ( CNC ), and bacterial cellulose ( BC ). It is hailed by the industry as a super new material in the green era.

Cellulose is the most abundant natural polymer on earth, with an annual biological output of hundreds of billions of tons. It comes from a wide range of sources and is renewable. We rely on an independent and controllable green preparation process to strip natural fibers down to the nanometer scale. The fiber diameter can reach tens of nanometers, retaining a large number of active hydroxyl structures, while giving the material a series of unique excellent properties: high aspect ratio, ultra-large specific surface area, ultra-high Young's modulus, quality It is light, high-strength, has low expansion coefficient and good light transmittance; it also has excellent biocompatibility, is completely biodegradable, non-toxic and safe, and can achieve diversified functions such as rheology regulation, reinforcement, barrier and suspension stability through surface modification, adapting to the customized needs of different industries.

Different from petroleum-based polymer materials, the greatest value of nanocellulose is its sustainability . The raw materials are taken from agricultural and forestry biomass. The production process is low-carbon and controllable. It can be degraded in the natural environment after use and has no persistent residues. It is in line with the ' double carbon ' strategy and the global plastic reduction trend. It is one of the core candidate materials to replace traditional petrochemical materials and achieve green industry upgrades.

Core performance advantages

1. Outstanding mechanical reinforcement properties : high strength and good rigidity. As a reinforcing filler, a small amount of addition can significantly improve the tensile strength and impact resistance of composite materials, reduce weight and enhance the stability of the base material.

2. Excellent rheology and suspension stability : It can form a three-dimensional network structure in the water system, with good thickening, thixotropic, suspension and anti-sedimentation effects. It does not require traditional chemical thickeners and the system is gentler and cleaner.

3. Barrier and film-forming properties : It can form a dense film, has excellent oxygen and water barrier capabilities, and is suitable for green packaging and barrier coatings; the film layer is light and thin and translucent, suitable for optical and flexible substrate scenarios.

4. Safe, friendly, and biocompatible : The raw materials are natural, low-irritation, and non-toxic. Food-grade and cosmetic-grade products can be directly used in human body and food contact scenarios; the porous structure is suitable for biomedical use, wound repair, and carrier sustained release.

5. Modifiable design : The rich hydroxyl groups on the surface provide modification space, which can be used to achieve hydrophilic / hydrophobic control and functional group loading through esterification, etherification, grafting, etc., and can be adapted to complex systems such as coatings, resins, and energy storage.

Diverse application scenarios

· Daily chemical care : As a natural rheology stabilizer and suspending agent, it can be used in essences, lotions, shower gels, sprays, and facial mask systems to improve skin feel and enhance the stability of particle suspension. It can replace traditional thickening systems such as Carbohydrate and make the formula cleaner.

· Food and green packaging : Food suspension stabilizers, beverage turbidity systems, degradable high-barrier packaging films, and fresh-keeping coatings can reduce plastic and extend shelf life.

· Coatings and polymer composite materials : Water-based coatings, inks, degradable plastics, and paper-based material reinforcements can improve coating adhesion, crack resistance, barrier properties, and reduce dependence on additives.

· New energy and energy storage : lithium battery separator coating, supercapacitor electrode, and airgel substrate to improve liquid retention, heat insulation, and structural stability.

· Papermaking, construction, water treatment : special paper reinforcement, lightweight thermal insulation aerogel, separation filtration membrane substrate.

· Biomedicine : cutting-edge directions such as medical dressings, drug sustained-release carriers, and tissue engineering scaffolds.
