Iranians Produce Nanocomposite from Sugarcane

Tehran, Iran | Posted on April 28th, 2014

The product has unique physical and mechanical properties and has many applications in packaging, glue making, medicine and electronic industries.

These nanofibers have simpler, faster and more cost-effective production method in comparison with other production methods. The size of the produced cellulose nanofiber has been reported about 39±13 nm while tension resistant of the nanocomposite produced from the nanofibers has been reported about 140 MPa. The produced nanocomposite has higher strength in comparison with the majority of biodegradable and non-biodegradable films. It seems that the produced nanocomposite can be considered an appropriate option for the elimination of artificial polymers and oil derivatives from packaging materials.

In order to produce the product, cellulose fibers were produced through mechanical milling method after separation and purification of cellulose from sugarcane bagasse, and then nanopapers were produced. Next, full cellulose nanocomposite was produced through partial dissolving method, and its characteristics were evaluated.

Results showed that as the time of partial dissolving increases, the diffusivity of the nanocomposite into vapor decreases due to the increase in glassy part (amorphous) to crystalline part. However, thermal resistant decreases as the time of partial dissolving increases because a decrease is observed in the crystalline part.

In addition, when cellulose microfibers turn into nanofibers, resistance against the tension of the produced films increases. The researchers believe that the reason for the increase is the reduction in fault points (points that lead to the fracture in cellulose fibers), increase in specific area, and integrity of nanofibers. Transparency of samples significantly increases as the size of particles decreases to nanometric scale.

Results of the research have been published in Carbohydrate Polymers, vol. 104, issue 1, January 2014, pp. 59-65.
