{"product_id":"cceamwcntp","title":"Multi-Wall Carbon Nanotubes (MWCNTs, \u003e99%) Powder as Conductive Electrode Additive, 50 g\/bottle, CCEAMWCNTP","description":"\u003cp\u003eMulti-walled carbon nanotubes (MWCNTs) are a critical conductive additive in electrochemistry, used primarily as a lower-cost, high-performance alternative to single-walled nanotubes. They consist of multiple nested graphene cylinders, providing a robust one-dimensional (1D) conductive network that is particularly effective at reinforcing electrodes and facilitating electron transfer in thick or high-loading systems. The critical features of MWCNT are: (1) \u003cstrong\u003eHigh Aspect Ratio\u003c\/strong\u003e: Their length-to-diameter ratio (\u0026gt;100) allows them to reach the percolation threshold at much lower concentrations than carbon black. (2) \u003cstrong\u003eThermal Stability\u003c\/strong\u003e: MWCNTs are stable up to \u0026gt;600°C, making them safe for use in high-temperature electrochemical cells or battery thermal runaway scenarios. (3) \u003cstrong\u003eChemical Versatility\u003c\/strong\u003e: The outer walls of MWCNTs can be easily functionalized (e.g., adding -COOH or -OH groups) to improve their dispersion in water-based binders or to attach specific proteins for biosensing. \u003c\/p\u003e\n\u003cp\u003e(1) In battery applications, especially for thick electrode, MWCNT penetrate these deep layers more effectively than spherical carbon black, reducing internal resistance and improving the rate capability (fast charging).\u003c\/p\u003e\n\u003cp\u003e(2) In electrolyzer and fuel cell application, MWCNTs are widely used as a substrate for Platinum (Pt) nanoparticles. Their high surface area and chemical stability improve the durability of the catalyst layer, resisting the corrosive, high-voltage conditions of fuel cell operation.\u003c\/p\u003e\n\u003cp\u003e(3) In supercapacitor system, MWCNTs films are highly conductive that functions as both the active material and the current collector, creating ultra-lightweight and flexible energy storage for wearable electronics.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 136.4px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCCEAMWCNTP (C-CEA-MWCNTP)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 10px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 10px;\"\u003e\u003cem\u003eAverage Size of MWCNT\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 10px;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003eI.D. = 3-5 nm,   O.D. = 8-15 nm    \u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.0935%;\"\u003e\u003cem\u003eMWCNT length\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e~10-50 um\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 35.6px;\"\u003e\u003cem\u003eSWCNT content in Carbon\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 35.6px;\"\u003e\n\u003cp\u003e\u0026gt;99%\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.0935%;\"\u003e\u003cem\u003eSurface Area\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%;\"\u003e\n\u003cp\u003e\u0026gt;233 m2\/g (BET)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.0935%;\"\u003e\u003cem\u003eTGA\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CCEAMWCNTP_TGA_160x160.png?v=1767518948\" alt=\"\" style=\"float: none;\"\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 33.0935%; height: 19.6px;\"\u003e\u003cem\u003ePackage Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 66.7266%; height: 19.6px;\"\u003e50 g\/bottle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eNotes\u003c\/strong\u003e: Please try to store the MWCNTs powder in a dry place (glovebox is the best option). \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eReferences\u003c\/strong\u003e: \u003c\/span\u003e\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003e\u003cspan\u003e\u003ca href=\"https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S0013468607010493\"\u003eQ.
