AI Article Synopsis
- This study presents a new and efficient method for integrating graphene oxide into quaternized hemicelluloses to create a composite film with excellent properties.
- The resulting films have a tensile strength of 43.83 MPa and exhibit smooth, uniform surfaces, indicating improved mechanical performance due to the addition of graphene oxide (GO).
- They demonstrate high sensitivity to humidity, allowing them to bend quickly in wet conditions and stretch in dry conditions, making them suitable for applications in biomedical fields, packaging, and humidity sensing.
Article Abstract
An effective and green method to incorporate graphene oxide into quaternized hemicelluloses to form a hemicelluloses based film was introduced in this study. Tight, homogeneous, and smooth surfaces of the film were obtained from the SEM image. Data on the mechanical properties of the films indicated that the hybrid films prepared from QH and GO (component of GO was 4.8%) exhibited a high tensile strength of 43.83 MPa. This finding suggested that addition of GO contributed to the desirable mechanical properties of the hybrid film. The hybrid films exhibited high sensitivity to humidity; they could be bent spontaneously under wet conditions within seconds and stretched under dry conditions. In addition, the results of DMA indicated that the storage modulus of the hybrid films had an order of magnitude change in value at different humidities. These characteristics show that films can be potentially used in bio-medicine, packaging materials, and humidity sensors.
