摘要

基于废纸制备了类石墨烯的碳材料，并通过表面活性剂进行了改性，然后将碳化的纸(CP)用洗衣粉改性的碳材料(CP/LD)运用到氨气(NH3)和甲醛(CH_2O)的检测中.实验结果表明：CP传感器显示出p型半导体的特性，CP/LD传感器显示出n型半导体的特性，但是CP传感器对两种气体的响应较小，改性之后CP/LD传感器对两种气体的响应显著提高，响应大小分别为2 021.59%和756.73%，提高了1 168倍和176倍，对85%的相对湿度(85%RH)表现出较好的抗干扰性.此外，两种传感器都表现出良好的可重复特性．

Abstract

In this paper

graphene-like carbon materials were prepared from waste paper and modified by surfactants. The carbonized paper(CP) and the carbon material modified with laundry detergent(CP/LD) were applied to the detection of ammonia(NH3) and formaldehyde(CH_2O). The experimental results show that the CP sensor shows the characteristics of p-type semiconductor and the CP/LD sensor shows the characteristics of n-type semiconductor

but the response of CP sensor is small for both gases

and the response of CP/LD sensing for both gases is significantly improved after modification

with the response size of 2 021.59% and 756.73% respectively

which is 1 168 and 176 times better

and 85% of relative humidity(85% RH) showed better resistance to interference. In addition

both sensors exhibit good reproducible properties.
