引言

基于界面分子作用的功能納米材料，在信息獲取、生態(tài)環(huán)境、新能源和健康醫(yī)療等領(lǐng)域應(yīng)用十分廣

泛。本文件描述了一種利用諧振微懸臂梁作為核心測量工具的諧振微質(zhì)量法，目的是為納米材料與氣體

界面作用熱力學(xué)參數(shù)和動力學(xué)參數(shù)的獲取提供一種標(biāo)準(zhǔn)的測量方法。該方法能夠有效避免傳統(tǒng)測量方法

的問題，獲得包括焓變、熵變、吉布斯自由能、活化能等在內(nèi)的熱力學(xué)參數(shù)和動力學(xué)參數(shù)，兼顧科學(xué)研

究和產(chǎn)業(yè)應(yīng)用的需求。
