Claim 3:
4. A nanofiber, comprising: a polyamide including at least one substituted phenyl group; wherein the nanofiber has an average diameter from 50 to 1000 nm; wherein the polyamide comprises a reaction product of (i) Monomer A, (ii) Monomer B, and (iii) Monomer C;
wherein Monomer A is selected from one or more compounds according to Formula (2), Monomer B is selected from one or more compounds according to Formula (3), and Monomer C is selected from one or more compounds according to Formula (4):, wherein R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, and R12 are each independently selected from H, a halogen, a saturated aliphatic radical having from 1 to 30 carbon atoms, an unsaturated aliphatic radical having from 1 to 30 carbon atoms, a nitro group, a carboxylic acid radical, or an ether radical, wherein at least one of R9, R10, R11, and R12 is a halogen, wherein R1 and R2 are each a chlorine atom or R3 and R4 are each a chlorine atom, and wherein Monomer A and Monomer B are different;
wherein X1 and X2 are each independently selected from a halogen;
wherein coefficient L is a relative number of moles for Monomer A with respect to a total number of moles for Monomers A through C, coefficient M is a relative number of moles of Monomer B with respect to the total number of moles for Monomers A through C, and coefficient N is a relative number of moles of Monomer C with respect to the total number of moles for Monomers A through C; and
wherein L+N=M, and L+M+N=1.
