In an article, author is Horwood, Linda, once mentioned the application of 86-86-2, Recommanded Product: 1-Naphthaleneacetamide, Name is 1-Naphthaleneacetamide, molecular formula is C12H11NO, molecular weight is 185.2218, MDL number is MFCD00004047, category is amides-buliding-blocks. Now introduce a scientific discovery about this category.
A route of alkylated carbon black with hydrophobicity, high dispersibility and efficient thermal conductivity
High dispersibility of carbon black (CB) is a great significance to its interfacial compatibility with organic or inorganic materials. We reported a type of alkyl-carbon black (aCB) nanoparticles with hydrophobic and lipophilic properties which were modified by Octadecyl isocyanate. The water contact angle of aCB was changed from 34.3 degrees/38.9 degrees to 102 degrees, which exhibited excellent dispersion ability in organic solutions. Covalent modification of aCB was confirmed by the increase of particle size from 474 nm to 499 nm and the loss of organic groups at temperatures from 30 degrees C to 800 degrees C. After reaction between CB and Octadecyl isocyanate, the characteristic band of isocyanate (eN=C=O) disappeared and formed new amide groups or carbamate, the decrease of O 1 s and C 1 s and the increase of N 1 s confirmed the alkyl chain grafted to the surface of CB. aCB showed an organic inorganic hybrid and multi-layer substance with disordered and high crystallization capacity.
