- Abstract
Sequential impregnation of a composite of poly(vinyl alcohol) and poly(acrylic acid) (PVA–PAA) into carbon‐nanotube fibers (CNTFs) and thermal condensation were investigated as a simple and efficient continuous textile engineering technique to prepare mechanically and electrically reinforced CNTFs. The CNTFs that were physically impregnated with PVA–PAA (<bold>PI‐CNTF–(PVA/PAA)</bold>) and the chemically crosslinked <bold>CNTF</bold> (<bold>CL‐CNTF–(PVA/PAA)</bold>) exhibited tensile strengths that were ∼1.6 and ∼2.1 times higher, respectively, and Young's moduli that were ∼1.3 and ∼2.3 times higher, respectively, than those of direct‐spun CNTFs. The electrical conductivity of <bold>PI‐CNTF–(PVA/PAA)</bold> and <bold>CL‐CNTF–(PVA/PAA)</bold> had values that were ∼1.5 and ∼1.7 times higher, respectively, than that of <bold>raw CNTFs</bold>. Moreover, the chemically crosslinked networks of <bold>CL‐CNTF–(PVA/PAA)</bold> resulting from the heat treatment enhanced the water resistance of the composite. POLYM.
