The invention relates to the technical field of electrochemical sensors and in particular to an alkane functionalized nanometer material based solid-polymer membrane ion-selectivity electrode. The solid-polymer membrane ion selectivity electrode comprises an electrode substrate and an ion-selectivity polymer membrane dispensed on the surface of the electrode substrate, and the ion-selectivity polymer membrane contains the alkane functionalized nanometer material. The alkane functionalized nanometer material is adopted to serve as a transmission component to reduce charge transfer resistance between the ion-selectivity membrane and the interface of the electrode substrate, stability of solid ion-selectivity electrode is improved, an ion carrier containing an alkane chain is fixed by the aid of alkane chain based hydrophobic effect, leakage of the ion carrier is alleviated, and service life of the sold-poly membrane ion-selectivity electrode is prolonged; in addition, a simple and feasible idea is provided for the solid ion-selectivity electrode with stable development and long service life.
