11001950 · 2021-05-11 · ·

One or more nanofiber yarns can be placed in contact with one or more nanofiber sheets. The nanofiber yarns, which include single-ply and multi-ply nanofiber yarns, provide added mechanical stability to a nanofiber sheet that decreases the likelihood of a nanofiber sheet wrinkling, folding, or otherwise becoming stuck to itself. Furthermore, the nanofiber yarns integrated with the nanofiber sheet can also act as a mechanism to prevent the propagation of tears through the nanofiber sheet. In some cases, an infiltrating material can be infiltrated into interstitial spaces defined by the nanofibers within both the nanofiber yarns and the nanofiber sheets. The infiltrating material can then form a continuous network throughout the nanofiber yarns and the nanofiber sheet.

A method for manufacturing an ultrasound generator with high laser-induced damage threshold is disclosed. The method includes forming an uncured prepolymer polydimethylsiloxane (PDMS) film on a substrate; spraying a solution containing light-absorbing nano-particles onto a surface of the uncured PDMS film, and then permeating the light-absorbing nano-particles into the uncured PDMS film; and curing the uncured PDMS film containing the light-absorbing nano-particles spatially distributed therein to form a composite film of nano-particles and PDMS, wherein the light-absorbing nano-particles permeated and diffused into the uncured PDMS film are dispersed such that a mean distance between the light-absorbing nano-particles in the PDMS film is substantially equal to or larger than a thermal diffusion length during a temporal width of an irradiation laser pulse, thus alleviating an exceedingly high thermal load, which can cause film damage or ablation, caused by nano-particles agglomerated or densely packed with a particle-to-particle mean distance smaller than the thermal diffusion length, ultimately resulting in the increase of laser-induced damage threshold and the maximum-available ultrasound output from the photoacoustic ultrasound generator.
