In this research, a carbon nanotube/layered double hydroxide nanocomposite was synthesized by an in situ growth route by electrostatic force. The prepared carbon nanotube/layered double hydroxide nanocomposite was successfully prepared and deposited on a stainless‐steel wire for the fabrication of the solid‐phase microextraction fiber. The fiber was evaluated for the extraction of phenolic compounds from water samples. Analytical merits of the method, under optimum conditions (extraction temperature: 75°C, extraction time: 30 min, desorption time: 2 min, desorption temperature 260°C, salt concentration: 10% w/v) are 0.01–300 ng/mL for the linear dynamic range and 0.005–0.08 for the limit of detection. In optimum conditions, the repeatability for one fiber ( n = 3), expressed as relative standard deviation, was between 6.5 and 9.9% for the phenolic compounds.
