Abstract
Carbon-based adsorbents used in current HDDs’ environmental-control-module (ECM) and recirculating filters have a close-end pore structure. Close-end pore structures usually have relatively low adsorption rate and adsorption capacity, which negatively impact the absorption effectiveness and efficiency. This invention proposes using Activated Carbon Aerogels to replace the conventional Activated Carbon for HDDs’ ECM and recirculating filters. Carbon Aerogels have open-end 3D-interconnected pore structures with a wider pore size distribution (ranging from micro-, meso- to macro pores) compared to Activated Carbons, enabling them to have faster adsorption rates, more effectiveness to a broader range of contaminants and much higher surface utilization (higher adsorption capacity). Additionally, Carbon Aerogels also have higher durability, reusability, and more regeneration cycles than Activated Carbons.
