1.introduction
Conductive ink is a revolutionary material that merges traditional printing with electronic functionality, enabling the creation of circuits, sensors, and antennas on various substrates. Its manufacturing is a precise process that combines specialized materials with controlled engineering.
2. Key Raw Materials
The formulation of a conductive ink is a careful balance of several components:
1. Conductive Functional Material:
This is the core ingredient that provides the electrical conductivity.
-
Silver (Ag): The most common choice. It offers excellent conductivity and environmental stability (does not oxidize easily). It is often used in the form of flakes (to create percolation networks) or nanoparticles (for sintering at lower temperatures).
-
Copper (Cu): A cost-effective alternative to silver. However, copper nanoparticles are highly prone to oxidation, which drastically reduces conductivity. This requires complex formulations with anti-oxidation agents.
-
Carbon-Based Materials: These are valued for flexibility and lower cost.
-
Graphene: Offers high conductivity, transparency, and mechanical strength.
-
Carbon Nanotubes (CNTs): Create conductive networks at very low loadings.
-
Graphite: The most economical option, but with higher electrical resistance.
-
-
Conductive Polymers: Such as PEDOT:PSS. These are used for transparent conductive films but generally have lower conductivity than metal-based inks.
2. Binder (Resin):
The polymer that forms the film matrix. It holds the conductive particles together and provides adhesion to the substrate (e.g., plastic, paper, glass). Examples include epoxy, polyimide, and acrylic resins.
3. Solvent:
The liquid carrier that dictates the ink's viscosity and rheology (flow properties). It evaporates during the curing process. The choice of solvent (e.g., water, organic solvents like cyclohexanone or ethanol) is critical for printability (inkjet vs. screen printing) and drying speed.
4. Additives:
Small quantities of specialty chemicals that modify specific ink properties.
-
Dispersants: Prevent the conductive particles from clumping together (agglomerating), ensuring a stable and homogeneous ink.
-
Rheology Modifiers: Control the flow characteristics (e.g., thickeners for screen printing paste).
-
Stabilizers: Prevent oxidation (crucial for copper inks) and degradation during storage.
-
Wetting Agents: Improve the ink's ability to spread and adhere to the substrate.
3. Production Steps
The transformation of these raw materials into a high-performance ink follows a meticulous, multi-stage process.
Step 1: Weighing and Pre-Mixing
Precise amounts of the conductive material, binder, solvent, and additives are weighed according to a proprietary recipe. These components are then loaded into a planetary mixer or a high-shear mixer for an initial rough blending. This creates a homogeneous paste and ensures no dry powder remains.
Step 2: Dispersion and Milling (The Most Critical Step)
Mere mixing is not enough. This step breaks apart particle agglomerates and uniformly distributes them throughout the binder solution. This is achieved using high-shear equipment:
-
Three-Roll Mill: The industry standard for high-quality pastes. The mixture is passed through three rollers rotating at different speeds. The immense shear force in the narrow gap between the rollers effectively separates, flattens (for flakes), and coats each particle.
-
Bead Mill: Suitable for large-volume production. The paste is agitated with small grinding beads, which smash the agglomerates through impact and shear.
This process is repeated until the desired fineness of grind and homogeneity are achieved.
Step 3: Dilution and Viscosity Adjustment
The milled paste is often too viscous. It is transferred to a mixing tank where additional solvents and additives are slowly incorporated under controlled agitation. This step fine-tunes the final viscosity, thixotropy, and surface tension to make it perfect for its target printing process (e.g., thin for inkjet, thick for screen printing).
Step 4: Quality Control (QC) Testing
Samples are taken from the batch and subjected to rigorous testing:
-
Fineness of Grind: Measured with a Hegman gauge to check for oversized particles.
-
Viscosity: Ensured it matches specifications for the intended printing method.
-
Sheet Resistance: The key electrical property. Ink is printed on a substrate, cured, and measured with a 4-point probe to confirm conductivity meets requirements.
-
Adhesion and Curing Tests: Verifies the ink's durability and performance on the target substrate.
Step 5: Filtration and Packaging
Once the batch passes QC, it undergoes filtration (especially critical for inkjet inks to prevent nozzle clogging). The finished ink is then packaged into airtight, light-resistant containers—such as syringes, cartridges, or jars—to prevent solvent evaporation and contamination before it reaches the customer.
