Surface Treatment
About AIMRSE
AIMRSE is a company dedicated to providing a comprehensive portfolio of thermal fillers and thermal interface materials (TIMs) for the global electronics, automotive, telecommunications, and energy sectors. With deep expertise in materials science and surface chemistry, AIMRSE bridges the critical gap between high-performance fillers and polymer matrices, enabling our customers to achieve unparalleled thermal management in their applications.
Our surface treatment services are tailored exclusively for thermal fillers — including but not limited to alumina (Al₂O₃), aluminum nitride (AlN), boron nitride (BN), silicon carbide (SiC), silicon nitride (Si₃N₄), and other advanced thermal fillers. We understand that the surface of a filler is the most critical interface dictating thermal conductivity, dispersion stability, viscosity control, and long-term reliability. Through precise surface modification and functionalization, we help customers overcome challenges such as filler agglomeration, high interfacial thermal resistance, and poor compatibility with organic matrices. Contact us today to discuss how our surface treatment expertise can elevate the performance of your thermal filler materials.
Surface Treatment Services
AIMRSE offers an exhaustive range of surface treatment services for thermal fillers, encompassing chemical, physical, and hybrid modification methodologies. Our services are meticulously designed to enhance filler-matrix compatibility, reduce interfacial thermal resistance, improve dispersion, control rheology, and maximize the intrinsic thermal conductivity of fillers in polymer composites. Below is the complete portfolio of surface treatment services we provide for thermal fillers — from conventional silanization to cutting-edge plasma fluorination and atomic-layer surface engineering. Each service can be customized to specific filler materials, particle sizes, and end-use requirements.
Silane Coupling Agent Modification
The most widely adopted and effective chemical surface treatment for thermal fillers. We utilize a broad portfolio of silane coupling agents to tailor filler surface chemistry. The treatment forms strong covalent bonds (Si–O–M) between the filler surface and the organic moiety, dramatically improving filler-matrix interfacial bonding.
Non-Covalent Functionalization
For applications where covalent modification is undesirable or where specific non-covalent interactions are required, we provide surface functionalization using π-π stacking, hydrogen bonding, electrostatic interactions, and van der Waals forces. This includes dopamine-assisted modification, poly(catechol/polyamine) (PCPA) coatings, and surfactant-assisted surface treatment.
Plasma Surface Treatment & Fluorination
Advanced dry-process surface modification using atmospheric or low-pressure plasma. We offer plasma activation (to introduce hydroxyl, carboxyl, amine groups) and plasma fluorination to graft fluorine atoms onto filler surfaces. Plasma fluorination creates highly electronegative surfaces that significantly improve electrical insulation while maintaining thermal conductivity.
Surface Grafting Polymerization
"Grafting from" and "grafting to" methodologies to attach polymer chains directly onto filler surfaces. This includes grafting of polymethacrylic acid, polyacrylamide, hyperbranched polymers, and tailored oligomers. The grafted polymer layer provides a robust interphase that enhances stress transfer, improves filler dispersion, and reduces interfacial thermal resistance.
Chemical Vapor Deposition (CVD) Coating
Gas-phase surface treatment using chemical vapor deposition to deposit ultra-thin, conformal coatings on thermal filler particles. We utilize alkoxysilane CVD, metal-organic CVD (MOCVD), and plasma-enhanced CVD (PECVD) to create self-assembled monolayers (SAMs) or nanoscale ceramic coatings with atomic-level precision.
Atomic Layer Deposition (ALD) Surface Engineering
Particle ALD technology for depositing conformal, pinhole-free nanoscale films on thermal filler particles. We can apply oxide layers, nitride layers, or hybrid coatings with sub-nanometer thickness control. ALD is ideal for creating core-shell filler architectures with precisely tuned surface properties.
Titanate & Aluminate Coupling Agent Treatment
Beyond silanes, we offer surface treatment using titanate coupling agents and aluminate coupling agents. These organometallic compounds are particularly effective for fillers that do not respond optimally to silanes, such as calcium carbonate, barium sulfate, and certain metal oxides.
Esterification & Hydrophobic Surface Treatment
Chemical modification of filler surfaces through esterification reactions between surface hydroxyl groups and organic acids (fatty acids, carboxylic acids) or alcohols. This treatment converts hydrophilic filler surfaces to hydrophobic, dramatically improving compatibility with non-polar polymer matrices like polyolefins and silicones.
Acid & Base Surface Activation
Controlled etching and surface activation using acidic (nitric, sulfuric, hydrochloric) or alkaline treatments to increase surface hydroxyl group density, remove surface contaminants, and create reactive sites for subsequent chemical modification. This is often a critical pre-treatment step for inert fillers like boron nitride.
