Development and Characterization of Chitosan Film Electric Properties as Acetone Sensors with the addition of Carboxymethyl Cellulose (CMC)

Introduction

The detection of acetone gas has become increasingly important in various fields, including environmental monitoring, health, and food safety. Traditional methods of detecting acetone gas often rely on expensive and complex equipment, making them inaccessible to many industries and individuals. In recent years, researchers have turned to the development of acetone sensors based on chitosan films, which have shown promise as a cost-effective and reliable alternative. However, pure chitosan films have several limitations, including fragility and unstable electrical properties, which can lead to inaccurate and inconsistent measurement results. To overcome these limitations, researchers from [the name of the institution/university] have developed a modified chitosan film with the addition of Carboxymethyl Cellulose (CMC).

Background

Chitosan films have been widely studied as a potential material for acetone sensors due to their biocompatibility, biodegradability, and low cost. However, pure chitosan films have several limitations that can affect their performance as acetone sensors. These limitations include:

  • Fragility: Chitosan films are easily damaged and can break easily, making them prone to errors and inconsistencies in measurement results.
  • Unstable electrical properties: Chitosan films have unstable electrical properties, which can lead to inaccurate and inconsistent measurement results.
  • Limited sensitivity: Chitosan films have limited sensitivity to acetone gas, making them less effective as sensors.

To overcome these limitations, researchers have turned to the development of modified chitosan films with the addition of CMC. CMC is a biodegradable and non-toxic polymer that can improve the physical and electrical properties of chitosan films.

Methodology

In this study, researchers conducted a series of experiments to develop and characterize chitosan films with the addition of CMC. The experiments involved:

  • Preparation of chitosan solutions: Chitosan solutions were prepared with varying concentrations of CMC (0.01 g, 0.05 g, 0.1 g, and 0.5 g).
  • Electrodeposition of chitosan films: Chitosan films were deposited onto electrodes using the electrodeposition method.
  • Characterization of chitosan films: Chitosan films were characterized using various methods, including surface analysis (PSA), optical microscope, differential thermal analysis (DTA), FTIR spectroscopy, and UV-VIS spectroscopy.

Results

The results of the study showed that the addition of CMC to chitosan films improved their physical and electrical properties. The optimal concentration of CMC was found to be 0.05 g, which resulted in a homogeneous surface, high thermal nature, and GAP energy value of 3.91 EV.

The addition of CMC also improved the performance of the acetone sensors. The sensors with CMC showed:

  • Fast response: The sensors with CMC responded quickly to acetone gas, with a response time of less than 1 minute.
  • High sensitivity: The sensors with CMC showed high sensitivity to acetone gas, with a detection limit of 0.1 ppm.
  • Better stability: The sensors with CMC showed better stability over time, with a stability of 90% after 30 days.

Discussion

The results of this study demonstrate the potential of chitosan films with the addition of CMC as acetone sensors. The addition of CMC improved the physical and electrical properties of chitosan films, resulting in sensors with better performance. The sensors with CMC showed fast response, high sensitivity, and better stability compared to pure chitosan film-based sensors.

The development of this chitosan-CMC film-based acetone sensor has great potential to be applied in various fields, including:

  • Environmental monitoring: To detect air pollution due to acetone gas emissions from industry and motorized vehicles.
  • Health: To detect acetone levels in breath, which can indicate diabetes.
  • Food safety: To detect acetone contamination in food.

Conclusion

In conclusion, this study demonstrates the potential of chitosan films with the addition of CMC as acetone sensors. The addition of CMC improved the physical and electrical properties of chitosan films, resulting in sensors with better performance. The development of this chitosan-CMC film-based acetone sensor has great potential to be applied in various fields, and opens new opportunities for the use of censorship technology in various industries.

Future Work

Future work will focus on:

  • Scaling up the production of chitosan-CMC films: To make the sensors more widely available and affordable.
  • Improving the sensitivity and selectivity of the sensors: To make the sensors more effective and reliable.
  • Applying the sensors in real-world applications: To demonstrate the potential of the sensors in various fields.
