The Influence of Pyrolidone Polyvinyl Dispersion Agents on Cellulose Nanocrystal Fillers from Corn Cobs in Natural Rubber Latex Films

Introduction

The use of natural materials in the rubber industry has gained significant attention in recent years due to the increasing awareness of environmental sustainability. One such natural material is cellulose nanocrystals (NCC) derived from corn cobs, which have been explored as a potential filler in natural rubber latex films. However, the dispersion of NCC in latex solution is crucial to achieve the desired mechanical properties in the final product. This study investigates the effect of polyvinylpyrrolidone (PVP) as a dispersing agent on NCC in natural rubber latex films.

Background

Natural rubber latex is a popular material used in various applications, including medical devices, gloves, and films. However, the use of synthetic chemicals in the production process can harm the environment. The incorporation of natural materials, such as NCC, can provide a sustainable solution to replace synthetic chemicals. NCC is a biodegradable and renewable material that can be derived from corn cobs, making it an attractive alternative to synthetic fillers.

Methodology

The study involved the preparation of natural rubber latex films using a coagulant dyeing method. The process consisted of pre-volcanization of natural rubber latex at 70°C, followed by the volcanization process at 110°C for 10 minutes. The NCC was dispersed in the latex solution using PVP as a dispersing agent. The concentration of NCC and PVP was varied to evaluate their effect on the mechanical properties of the films.

Results

The results showed that an increase in the concentration of PVP resulted in an increase in cross-linking density of the latex films. However, the mechanical testing revealed that the maximum value of mechanical properties was achieved at a PVP loading of 3 grams. The analysis of Electron Microscopy (SEM) scanning and Fourier Transform Infrared (FTIR) analysis confirmed that PVP had been well dispersed in the latex films, with several detected functional groups.

Optimization of Mechanical and Physical Conditions

The optimization of mechanical and physical conditions in natural rubber latex films was achieved at a concentration of NCC dispersion of 20% mixed with 3 grams of PVP. In this condition, the cross-linking density values, tensile strength, extension at break, 200% modulus, and 300% modulus reached 9.36 x 10^-5 2mc; 12.58 MPA; 770%; 1.20 MPa; and 1.45 MPa, respectively. This shows that the use of PVP as a dispersing agent has been proven effective in improving the quality of natural rubber latex films.

Discussion

The study highlights the potential of using natural materials, such as NCC from corn cobs, in the rubber industry. The good dispersion of NCC in latex solution is crucial to achieve the desired mechanical properties in the final product. PVP plays an important role in increasing the ability of NCC dispersibility, which causes an increase in cross-linking density and the mechanical properties of the film.

Conclusion

This study provides new insights on the use of natural ingredients in improving the quality of natural rubber latex products. The results show that the combination of NCC and PVP can be used as alternative raw materials in the rubber industry. The products produced not only have better physical endurance but also have a positive impact on the environment, thus attracting producers to adopt this technology.

Future Directions

The results of this study can open the way for further innovation in the development of rubber products. The use of NCC and PVP can be explored in various applications, including medical devices, gloves, and films. Additionally, the study highlights the importance of sustainability in the rubber industry, and the use of natural materials can contribute to a more environmentally friendly production process.
