Silica Nanofibers: Silicon Dioxide (SiO2) Nanofiber Solutions

Surface area and porosity are mainly a function of fiber diameter, packing density, and any post-processing applied to the mat — thinner fibers and looser mats generally yield higher surface area and porosity. TruSpin's AC electrospinning platform gives precise control over fiber diameter and collection method (including roll-to-roll and direct-to-substrate deposition), so surface area and porosity can be engineered to your application rather than fixed to one spec. For filtration or catalyst-support uses where surface area is a critical driver, TruSpin's team can define target specifications with you. Request a quote through the services page with your application details for an exact spec.

TruSpin's AC electrospinning platform gives precise control over fiber diameter, alignment, porosity, and cross-linking, so silica diameter can be tuned to your application rather than fixed to one size. Electrospun nanofibers generally span roughly 40 to 2,000 nanometers depending on process parameters, and silica can be produced within that range. Since diameter affects surface area, mechanical properties, and filtration performance, the ideal diameter depends on use: finer diameters typically maximize surface area for catalytic or filtration work, while larger diameters may suit structural or insulation uses. TruSpin's technical team can help confirm feasibility for your project before production begins.

Orders are typically processed within 1–2 business days. Delivery times vary by location, but most orders arrive within 3–7 business days. You’ll receive tracking details once your order ships.Silica (silicon dioxide) nanofibers are used in filtration, thermal insulation, catalysis, and composite reinforcement. Their high surface-area-to-volume ratio and chemical inertness suit fine-particulate filtration, while their porous structure makes them effective catalyst supports with ample surface area for active-site dispersion. As composite reinforcement, they add mechanical strength or thermal resistance; in insulation, silica nanofiber mats trap air within a fine fiber network to reduce thermal conductivity. TruSpin produces silica nanofibers on its AC electrospinning platform, with precise control over fiber diameter and porosity to match your application. Custom diameter, density, or surface treatment is available on request.

Silica is inherently thermally stable, with a melting point above 1,600°C, making it well suited to high-heat environments where organic and many polymer fibers fail. Actual effective operating temperature depends on the application, surrounding atmosphere, and any additives incorporated into the fiber. TruSpin's AC electrospinning process, with high additive tolerance and precise process control, can tailor silica compositions toward specific thermal-performance requirements for filtration, insulation, and catalyst-support applications. For a validated temperature threshold, TruSpin's team can characterize and test a composition against your exact operating conditions. Reach out through the services page with your target environment for a recommendation.

Yes. Silica nanofibers are an established catalyst support because of their high surface-area-to-volume ratio, chemical inertness, and thermal stability, which help maximize dispersion and durability of active catalytic sites. The nanofiber format's continuous, high-aspect-ratio structure creates an open, interconnected network that improves reactant accessibility and reduces pressure drop compared to packed particulate supports. TruSpin's AC electrospinning platform can engineer silica compositions with specific porosity, fiber diameter, and additive incorporation to tailor a support to your active-site loading or reaction environment. If you're evaluating silica for a catalytic application, TruSpin can discuss your target conditions and composition options.
