Controlled 1um Particle Size

The uniform particle specification supports repeatable colloidal assembly, optical testing and comparative material research.

Spherical PS Structure

The polystyrene matrix provides good optical contrast, stable particle morphology and compatibility with common colloidal processing methods.

Convenient 5% Suspension

The 5% solid content supports direct dilution, concentration adjustment, coating trials and pilot-scale processing.

Suitable for Ordered Particle Arrays

SPS1UM-10 can be evaluated for monolayer and multilayer particle structures, periodic arrays and microsphere templates.

Stable Bulk Supply

SHBC supports sample testing, customized specifications, pilot orders and long-term batch production.

Applications in Photonic Crystal Research

SPS1UM-10 can be evaluated for:

• Colloidal photonic structures

• Two-dimensional particle arrays

• Ordered microsphere films

• Photonic lattice research

• Optical scattering studies

• Periodic surface structures

• Structural optical material development

• Photonic and plasmonic composite research

• Colloidal self-assembly

• Microstructured coating development

• Optical sensor research

The final optical response depends on particle arrangement, layer thickness, refractive index, substrate and surrounding medium.

Why Choose 1um PS Microspheres?

Compared with smaller nanoparticles, 1 µm microspheres are easier to observe, recover and arrange during research.

Key benefits include:

• Convenient microscopic observation

• Easier particle recovery

• Suitable for large-period colloidal arrays

• Stable spherical morphology

• Good optical scattering performance

• Flexible concentration adjustment

• Compatibility with different substrates

• Suitable for template and coating research

• Support for laboratory-to-pilot scale-up

The 1 µm size may produce optical behavior different from smaller particles commonly used for visible structural colors. Customers should verify the required wavelength range and optical response experimentally.

Colloidal Assembly and Template Applications

SPS1UM-10 can be evaluated using:

• Drop casting

• Spin coating

• Vertical deposition

• Horizontal deposition

• Evaporation-induced assembly

• Air–water interface assembly

• Template-assisted assembly

• Layer-by-layer deposition

The microspheres can also serve as removable or permanent templates for preparing:

• Ordered surface patterns

• Porous materials

• Inverse structures

• Microstructured films

• Metal-coated particle arrays

• Etching and lithography masks

• Composite optical materials

Optical and Particle Research Applications

In addition to photonic crystal research, SPS1UM-10 can be evaluated for:

• Light-scattering studies

• Optical microscopy research

• Particle tracking

• Instrument performance evaluation

• Filter membrane testing

• Fluid dynamics research

• Surface deposition studies

• Colloidal interaction research

• Microfluidic particle studies

• Educational demonstrations

Use as a certified particle-size calibration standard requires confirmation of batch-specific certification and traceability.

Factors Affecting Assembly Quality

Important processing parameters include:

• Particle size distribution

• Microsphere concentration

• Dispersion stability

• Surface charge

• Substrate cleanliness

• Substrate surface energy

• Deposition volume

• Temperature

• Humidity

• Evaporation rate

• Surfactant concentration

• Ionic strength

• Number of particle layers

Stable processing conditions help improve array uniformity and reduce cracks, voids and irregular packing.

Processing and Handling Guidance

• Mix gently before sampling.

• Fully redisperse settled particles.

• Avoid dust and particulate contamination.

• Use clean containers and substrates.

• Optimize concentration before coating.

• Control temperature and humidity during drying.

• Avoid excessive surfactant or salt addition.

• Do not allow the stock suspension to dry.

• Avoid freezing unless permitted by the specification.

• Confirm substrate compatibility before scale-up.

Mild sonication may be evaluated when additional dispersion is required. Avoid overheating during sonication.

Quality Control and Batch Documentation

Available documentation may include:

• Certificate of Analysis

• Safety Data Sheet

• Product specification

• Particle size information

• Solid-content information

• Batch identification
