Nanocellulose Preparation

Nanocellulose is a nanoscale fibrous material extracted from natural cellulose or obtained through chemical and physical modification. Its key feature is having at least one dimension within the nanoscale range (1–100 nm) while retaining the chemical properties and biodegradability of cellulose. As a renewable, eco-friendly, and high-performance nanomaterial, nanocellulose has attracted widespread attention in recent years. It not only inherits the biodegradability and renewability of cellulose but also exhibits excellent mechanical, thermal, and optical properties due to its unique nanoscale structure. Nanocellulose is gradually becoming a key component in advanced materials and green technologies. BOC Sciences is dedicated to providing global biomimetic materials researchers and manufacturers with comprehensive nanocellulose production, synthesis, and development services, including the custom preparation, analysis, modification, and application support for bacterial nanocellulose, cellulose nanocrystals, cellulose nanofibers, and their derivatives.

FAQs
Frequently Asked Questions
What is nanocellulose?
Nanocellulose is a highly versatile material derived from cellulose, consisting of nanoscale fibrils or crystals. It exhibits remarkable mechanical strength, large surface area, and biodegradability. Nanocellulose is used in advanced materials, composites, coatings, hydrogels, and electronics. Its unique nanoscale structure enables applications that require high tensile strength, transparency, or enhanced barrier properties, making it valuable across pharmaceuticals, food, packaging, and biomedical industries.
What is the difference between cellulose and nanocellulose?
Cellulose is a natural polymer composed of glucose units forming fibers, while nanocellulose refers to cellulose processed into nanoscale forms such as cellulose nanocrystals (CNCs) or cellulose nanofibers (CNFs). Nanocellulose has significantly higher surface area, mechanical strength, and tunable properties compared to bulk cellulose. Its nanoscale dimensions enable applications in high-performance composites, drug delivery systems, and advanced coatings, where conventional cellulose cannot provide sufficient strength or surface functionality.
How to make nanocellulose?
Nanocellulose is produced by mechanical, chemical, or enzymatic treatment of cellulose. Mechanical methods include high-pressure homogenization, grinding, or ultrasonication to break down fibers. Chemical methods, such as acid hydrolysis or TEMPO-mediated oxidation, selectively remove amorphous regions, yielding nanocrystals or nanofibers. Enzymatic treatments use cellulases to assist fiber disintegration. The production method affects particle size, crystallinity, surface chemistry, and suitability for specific industrial or biomedical applications.
What are the main properties of nanocellulose?
Nanocellulose exhibits high tensile strength, low density, large surface area, and biodegradability. It can form transparent films, hydrogels, or reinforced composites. Surface modification allows functionalization for adhesion, water absorption, or drug delivery. Its nanoscale structure also enables rheological control in suspensions. Non-toxic and renewable, nanocellulose finds use in coatings, inks, food stabilization, biomedical scaffolds, and green materials, combining mechanical performance with sustainability.
What are the different types of nanocellulose?
The main types of nanocellulose include cellulose nanocrystals (CNCs), cellulose nanofibers (CNFs), and bacterial nanocellulose (BNC). CNCs are rigid rod-like structures obtained via acid hydrolysis. CNFs are long, flexible fibrils produced by mechanical or enzymatic treatments. BNC is biosynthesized by bacteria, forming a pure, highly crystalline network. Each type has unique dimensions, crystallinity, and surface chemistry, influencing applications in composites, hydrogels, electronics, and biomedical fields.
What is nanocellulose used for?
Nanocellulose has broad industrial and biomedical applications. It reinforces composites, improves barrier properties in packaging, stabilizes emulsions in food, and enhances rheology in coatings or inks. In biomedicine, it serves as wound dressings, drug carriers, or tissue scaffolds. Its nanoscale structure allows use in electronics, sensors, and flexible films. Renewable, biodegradable, and biocompatible, nanocellulose is increasingly integrated into green materials, sustainable packaging, cosmetics, and energy storage, providing functional performance that traditional cellulose cannot achieve.
What is cellulose nanocrystals?
Cellulose nanocrystals (CNCs) are rigid, rod-shaped nanostructures extracted from cellulose fibers via acid hydrolysis. They possess high crystallinity, mechanical strength, and large surface area. CNCs can form stable suspensions, transparent films, or reinforce composites. Their surface chemistry allows functionalization for applications in coatings, adhesives, biomedical scaffolds, and sensors. CNCs are lightweight, renewable, and biodegradable, making them a versatile nanomaterial for high-performance applications in packaging, electronics, and biomedicine.
How to make cellulose nanocrystals?
Cellulose nanocrystals are commonly produced through controlled acid hydrolysis, which removes amorphous regions of cellulose fibers. Sulfuric or hydrochloric acids are used, resulting in rod-like crystalline domains. Post-hydrolysis steps include washing, neutralization, and sonication to obtain uniform suspensions. Alternative methods include enzymatic pretreatment or mechanical shearing to assist fiber breakdown. Production parameters such as temperature, acid concentration, and time affect particle size, crystallinity, and surface charge, which determine the CNCs' performance in specific applications.
What is cellulose nanofiber?
Cellulose nanofibers (CNFs) are long, flexible nanoscale fibrils derived from cellulose fibers. They have high aspect ratios, mechanical strength, and a large surface area, allowing them to form entangled networks and hydrogels. CNFs can be chemically modified to enhance compatibility with polymers or for specific applications in coatings, composites, biomedical scaffolds, and paper reinforcement. Compared to CNCs, CNFs are less crystalline but more flexible, making them suitable for applications requiring structural reinforcement, viscosity control, or functional surface properties.
How to make cellulose nanofiber?
Cellulose nanofibers are produced by mechanical disintegration of cellulose fibers, often combined with chemical or enzymatic pretreatments. Mechanical methods include high-pressure homogenization, microfluidization, grinding, or ultrasonication. Chemical pretreatments like TEMPO-mediated oxidation introduce charges to facilitate fiber separation. Enzymatic treatment with cellulases softens fibers and reduces energy consumption. The choice of method affects fiber diameter, length, surface chemistry, and functional properties, determining suitability for composites, films, hydrogels, or biomedical applications.
