Film including polymeric elements interconnecting particles

A film comprising a polymeric material and a plurality of particles dispersed therein at a volume loading of greater than about 50 percent, the polymeric material comprising a plurality of elongate polymeric elements interconnecting the particles, each elongate polymeric element in a sub-plurality of elongate polymeric elements in the plurality of elongate polymeric elements comprising a plurality of spaced apart elongate portions, each elongate portion in the plurality of spaced apart elongate portions conforming and bonded to a particle in the plurality of particles along an entire length of the elongate portion with the polymeric element extending away from the particle from opposite ends of the elongate portion.

A multilayer film comprising a porous middle layer disposed between, and bonded to, opposing non-porous first and second protective layers, the porous middle layer comprising:

• a plurality of elongate polymeric elements interconnecting a plurality of hollow particles;
• and
• a plurality of interconnected voids defined by the pluralities of elongate polymeric elements and hollow particles, wherein a real part of a dielectric constant of the film at a frequency of about 2.5 GHz is less than about 1.4.

A multilayer film comprising a middle layer disposed between, and bonded to, opposing first and second protective layers, the middle layer comprising a plurality of elongate polymeric elements interconnecting a plurality of particles, for at least a pair of first and second particles in the plurality of particles and for each elongate polymeric element in a sub-plurality of elongate polymeric elements in the plurality of elongate polymeric elements, a first end of the element terminates at the first particle and an opposing second end of the element terminates at the second particle.

A multilayer film comprising a middle layer disposed between, and bonded to, opposing first and second layers, the middle layer comprising a plurality of hollow particles dispersed therein at a volume loading of greater than about 50 percent, the multilayer film having an elongation at break of at least 15% at a tensile load rate of no more than about 5 Newtons per second at room temperature, wherein a bending of the multilayer film at a bend location over an inner radius of at most 1.5 mm results in no, or very little, damage to the middle layer at the bend location.
