The present invention includes methods of making a nanocellulosic composition comprising one or more nanocellulosic components, wherein the one or more nanocellulosic components comprise a micron-scale cellulose or cellulose nanofibrils (CNF), the method comprising the steps of: creating a nanocellulosic slurry by combining the one or more of nanocellulosic components with a liquid component; and exposing the nanocellulosic slurry to a drying condition, wherein the drying condition comprises microwave radiation, thereby creating a nanocellulosic composition. The present invention also includes compositions comprising cellulose (nanocellulosic compositions), wherein the nanocellulosic compositions have an internal void space of about 5% to about 95% by volume.

A crosslinked polyolefin separator having a ratio (A/B) of storage modulus G′ (A) to loss modulus G″ (B) of 2 or more, at a range of the frequency of the crosslinked polyolefin separator of 1 rad/s or less, in the frequency-loss/storage modulus curve. The crosslinked polyolefin separator is controlled to have a high ratio of storage modulus to loss modulus, and thus maintains its elasticity even at high temperature. Therefore, it is possible to provide a separator having improved safety.
