Dynamic mechanical properties for polyester/microcellulose and polyester/nanocellulose

In this article it is presented the influence of nanocellulose and microcellulose to mechanical and thermal properties of their composite with polyester. It used DMA method to determine the elastic and plastic behavior of polyester/nanocellulose and polyester/microcellulose composite. It is determined storage modulus, loss modulus, damping factor and glass transition temperature for polyester/microcellulose and polyester/nanocellulose composite. For all composite can be observed a good improvement of mechanical and thermal properties. Polyester/nanocellulose composites showed better properties than polyester/microcellulose composite due to strongest chemical bonds between nanocellulose and polyester matrix.
