PEROVSKITE FILM COATER AUTOMATIC BLADE AIR KNIFE N2 PROTECTION

RESEARCH GRADE EQUIPMENT

Product Overview

This Perovskite Film Coater is a dedicated automatic blade coating with air knife system engineered specifically for perovskite thin film preparation. The integrated air knife assembly—supplied with nitrogen gas—creates an nitrogen inert atmosphere protection barrier that prevents material oxidation during the critical coating and drying stages. The coater features a 0.8 mm vacuum hole array across an anodized hard aluminum substrate plate with ±1 μm flatness precision, ensuring ultra-thin substrates remain flat without sagging. The magnetic flip-cover blade mechanism, snap-fit wire bar system, and detachable air knife module with universal adjustable bracket enable rapid cleaning, maintenance, and flexible setup reconfiguration. Driven by a servo motor for smooth and stable operation at both high and low coating speeds, this instrument is purpose-built for perovskite thin film deposition, lithium battery electrode slurry coating, and new material layer preparation in research laboratories.

Key Features & Advantages

Nitrogen Air Knife Oxidation Barrier: The air knife assembly delivers nitrogen gas flow over the freshly coated film, creating an inert atmosphere shield that prevents oxygen and moisture-induced degradation of air-sensitive perovskite materials during the critical drying phase.
Ultra-Flat Anodized Aluminum Substrate Plate: Hard anodized aluminum construction with ±1 μm flatness precision and 0.8 mm vacuum holes ensures ultra-thin and flexible substrates remain perfectly flat during coating, eliminating sag-induced thickness variations.
Magnetic Flip-Cover Blade with Snap-Fit Wire Bar: The magnetic flip-cover design allows rapid blade access for cleaning without disassembly, while the snap-fit wire bar system enables quick changes between coating configurations for multi-material experimental workflows.
Servo Motor Precision Drive: The servo motor provides smooth, vibration-free operation across the full speed range, delivering consistent coating thickness and uniformity essential for reproducible perovskite device fabrication.

APPLICATION SCOPE: Perovskite thin film deposition for solar cell and optoelectronic device research. Lithium battery positive and negative electrode slurry coating. Functional film and new material coating preparation. Organic semiconductor and polymer thin film fabrication. Compatible with rigid and flexible substrates across materials science and energy device research.

MODEL SELECTION: Three configurations are available: (1) Benchtop Coater with snap-fit wire bar, magnetic flip-cover blade, vacuum ultra-flat plate, servo motor, and fine-adjustment pressure head; (2) Floor-Standing Coater with all benchtop features plus wheel-mounted mobile frame; (3) Cabinet Coater integrating all benchtop and floor-standing functions with a marble coating table for the highest flatness precision.

IMPORTANT NOTICE: Connect nitrogen supply to the air knife assembly before initiating coating of air-sensitive materials to establish the inert atmosphere barrier. Verify vacuum pump connection and confirm substrate hold-down on the anodized aluminum plate before coating. Clean the magnetic flip-cover blade and snap-fit wire bar thoroughly after each use to prevent cross-contamination between materials. The detachable air knife module should be periodically inspected for nozzle alignment. For perovskite film preparation, conduct coating operations in a dry, controlled environment whenever possible. For detailed operational and safety instructions, consult the user manual prior to first use.
