The Influence of Chitosan Addition on Thermal Properties and Function Clusters of Biopolymer Films from Palm Stem Starch (Elaeis Guineensis) Using Sorbitol Plasticizer

Introduction

The increasing demand for sustainable and environmentally friendly materials has led to the development of biopolymer films from renewable resources such as palm stem starch (Elaeis guineensis). Biopolymer films have shown great potential in various applications, including packaging, biomedical, and pharmaceutical industries. However, the properties of biopolymer films can be improved by adding various additives, such as chitosan, which is a biodegradable and non-toxic polymer derived from chitin. This study aims to explore the influence of chitosan addition on the thermal properties and functional groups of biopolymer films made from palm stem starch using sorbitol plasticizer.

Materials and Methods

The biopolymer films were prepared by mixing palm stem starch and sorbitol plasticizer in a comparison variation of 2: 0.8; 2: 1.0; and 2: 1.2 (g/ml). The mixture was then printed on an acrylic plate and dried in the oven at 40 °C for 24 hours. The resulting films were then characterized using various techniques, including swelling test, Differential Scanning Calorimetry (DSC), Differential Thermal Analysis (DTA), and Fourier Transform Infrared (FT-IR) spectroscopy.

Results and Discussion

The results of the swelling test showed that the biopolymer film with a ratio of 2: 0.8 (g/ml) had the highest % swelling value of 133.59 %. The addition of chitosan was found to increase the water resilience of the film, reaching an increase of 63.176%. This shows that chitosan not only improves the physical nature of the film but also contributes to the resistance to humidity.

The analysis of thermal properties of the film using DSC and DTA showed a significant tendency to increase after the addition of chitosan. The endothermic temperatures increased to 115.75 °C, while exothermic temperatures increased to 394.56 °C. The result of the DTA showed the endothermic temperature of 150 °C and the exothermic temperature of 470 °C. This increase in temperature indicates that the addition of chitosan strengthens thermal interactions in biopolymer films, thereby increasing the thermal stability of this material.

The analysis using FT-IR spectroscopy indicated that there is a physical interaction between chitosan and the biopolymer film, but no formation of a new functional group. This can be seen from the absorption band identified in the same wave number, namely OH/NH at 3410.15 cm-1, CH at 2924.09 cm-1, and C-O/C-N at 1026.13 cm-1. The absence of the formation of a new functional group shows that chitosan does not change the basic chemical structure of the biopolymer film, but makes a positive contribution to physical and thermal properties.

Conclusion

This study shows that the addition of chitosan into the biopolymer film from palm stem starch not only increases water security but also the thermal nature of the film. This makes this biopolymer film more applicable in various fields, including environmentally friendly packaging and biodegradable materials. The potential use of chitosan as an additional material in making biopolymer films can answer challenges in industries that prioritize sustainability and resource efficiency.

Future Directions

The results of this study suggest that the addition of chitosan can improve the properties of biopolymer films made from palm stem starch. However, further studies are needed to explore the potential applications of these biopolymer films in various industries. Additionally, the effects of different concentrations of chitosan on the properties of biopolymer films should be investigated to optimize the formulation of these materials.

Recommendations

Based on the results of this study, the following recommendations are made:

  1. The use of chitosan as an additive in making biopolymer films from palm stem starch can improve the properties of these films, including water security and thermal stability.
  2. Further studies should be conducted to explore the potential applications of these biopolymer films in various industries, including packaging, biomedical, and pharmaceutical industries.
  3. The effects of different concentrations of chitosan on the properties of biopolymer films should be investigated to optimize the formulation of these materials.

Limitations

This study has several limitations, including:

  1. The use of a single type of plasticizer, sorbitol, which may not be representative of all plasticizers.
  2. The limited number of samples used in this study, which may not be representative of all possible variations of biopolymer films.
  3. The lack of control over the processing conditions, which may affect the properties of the biopolymer films.

Future Research Directions

The results of this study suggest that further research is needed to explore the potential applications of biopolymer films made from palm stem starch and chitosan. Some potential research directions include:

  1. Investigating the effects of different concentrations of chitosan on the properties of biopolymer films.
  2. Exploring the potential applications of these biopolymer films in various industries, including packaging, biomedical, and pharmaceutical industries.
  3. Developing new formulations of biopolymer films using different types of plasticizers and additives.

Conclusion

In conclusion, this study shows that the addition of chitosan into the biopolymer film from palm stem starch not only increases water security but also the thermal nature of the film. This makes this biopolymer film more applicable in various fields, including environmentally friendly packaging and biodegradable materials. The potential use of chitosan as an additional material in making biopolymer films can answer challenges in industries that prioritize sustainability and resource efficiency.
