LASER-PERFORATED POROUS SOLID-STATE FILMS AND APPLICATIONS THEREOF

摘要

The disclosure relates, in one aspect, to porous solid-state films with controlled pore structures obtained by laser perforation. A thin laser-perforated film can comprise a slab defining a plurality of pores distributed in a predetermined arrangement, the plurality of pores having a distribution of sizes bound by a predetermined magnitude. In an aspect, the plurality of pores are formed in the slab with a laser having a wavelength less than about 400 nm and the slab has a transmission of the laser light of equal to or less than about 70% measured at a thickness of the slab of 100 micrometer or less.

主权项

1. A perforated film comprising:
a slab defining a plurality of pores distributed in a predetermined arrangement, the plurality of pores having a mean diameter less than about 50 μm; wherein the plurality of pores are formed in the slab with a laser having a wavelength less than about 400 nm and the slab has a transmission of the laser light of equal to or less than about 70% measured at a thickness of the slab of 100 micrometer or less; and wherein the slab has a high temperature melt integrity (HTMI) equal to or exceeding about 180° C.
