A simple, fast, and ecofriendly polyol method for the synthesis of silver nanowires (AgNWs) with high aspect ratios is presented. Besides, the effects of reaction parameters on the synthesis process, namely reaction temperature, PVP molecular weight, sodium chloride content, as well as solution mixing rate on the morphology and dimensions of silver nanowires, are thoroughly investigated. AgNWs were fully characterized using FE-SEM, TEM, XRD, FT-IR, and UV–Vis analysis and showed an average diameter of 50 nm. Polymer nanocomposites were fabricated through mixing and curing of the AgNWs, PDMS, and curing agents. The prepared nanocomposites were analyzed microscopically, and their electrical conductivity was measured. PDMS containing 25 wt% AgNWs was considered as an optimal composite, mainly because it possessed a combination of flexibility and transparency, accompanied by the high electrical conductivity of 5840.4 S/cm. This composite can be deemed as a potential candidate in lab-on-a-chip and biosensing applications.

提出了一种简单、快速且环保的多元醇方法，用于合成具有高纵横比的银纳米线 (AgNW)。此外，还深入研究了反应参数对合成过程的影响，即反应温度、PVP 分子量、氯化钠含量以及溶液混合速率对银纳米线形貌和尺寸的影响。使用 FE-SEM、TEM、XRD、FT-IR 和 UV-Vis 分析对 AgNW 进行了全面表征，平均直径为 50 nm。聚合物纳米复合材料是通过混合和固化 AgNW、PDMS 和固化剂来制造的。对制备的纳米复合材料进行微观分析，并测量其电导率。含有 25 wt% AgNWs 的 PDMS 被认为是最佳复合材料，主要是因为它兼具柔韧性和透明性，同时具有 5840.4 S/cm 的高电导率。这种复合材料可被视为芯片实验室和生物传感应用的潜在候选者。
