A polyolefin material that comprises a thermoplastic composition, the composition containing a continuous phase that includes a polyolefin matrix polymer and a nanoinclusion additive dispersed within the continuous phase in the form of discrete domains, the composition further including a beta-nucleating agent, wherein a porous network is defined within the thermoplastic composition that includes a plurality of nanopores.
A method for forming a polyolefin material, the method comprising:
- forming a thermoplastic composition that contains a continuous phase that includes a polyolefin matrix polymer and a nanoinclusion additive dispersed within the continuous phase in the form of discrete domains, the composition further including a beta-nucleating agent;
- and
- solid state drawing the thermoplastic composition to form a porous network therein, the porous network including a plurality of nanopores.
