Title: Design of Ultrastiff Organosilicate Hybrid Glasses

Abstract

Abstract Hyperconnected hybrid organosilicate glass networks formed by hyperstiff precursor molecules with certain geometrical characteristics can lead to exceptional elastic properties superior to that of fully dense silica. Carbon‐ and silicon‐containing precursors with defined molecular planarity are introduced and a new design strategy where both the network connectivity and the precursor geometry are effectively utilized to enhance elastic properties is proposed. The geometrical features rendering a precursor molecule as hyperstiff are identified through molecular dynamics simulations and constraint analyses by calculating the degree of nonaffine deformations. Nonaffine deformations have not been previously examined for organosilicate hybrid glass networks and are a fundamental new approach to reveal the combined impact of precursor geometry and connectivity on the mechanical behavior of hybrid glass networks.

Hyperconnected molecular glass network architectures with exceptional elastic properties

Journal Article Burg, Joseph A. ; Oliver, Mark S. ; Frot, Theo J. ; ... - Nature Communications

Hyperconnected network architectures can endow nanomaterials with remarkable mechanical properties that are fundamentally controlled by designing connectivity into the intrinsic molecular structure. For hybrid organic–inorganic nanomaterials, here we show that by using 1,3,5 silyl benzene precursors, the connectivity of a silicon atom within the network extends beyond its chemical coordination number, resulting in a hyperconnected network with exceptional elastic stiffness, higher than that of fully dense silica. The exceptional intrinsic stiffness of these hyperconnected glass networks is demonstrated with molecular dynamics models and these model predictions are calibrated through the synthesis and characterization of an intrinsically porous hybrid glass processedmore »« less

Role of Carbon Bridge Length of Organosilicate Precursors on the Atmospheric Plasma Deposition of Transparent Bilayer Protective Coatings on Plastics

Here, we demonstrate the deposition of transparent organosilicate protective bilayer coatings on poly methyl methacrylate (PMMA) substrates with different carbon chain length dipodalsilane precursors using atmospheric plasma deposition in ambient air. The bottom adhesive layer was a hybrid organosilicate coating deposited using either only carbon bridge organosilicate precursor or accompanied with a ring structure 1,5-cyclooctadiene precursor. The top layer was a dense silica coating with high elastic modulus and hardness deposited with only carbon bridge precursor. The adhesion energy of bottom layer increased with increasing carbon bridge length of precursors while the density, hardness, and elastic modulus of top hardmore »« less

Influence of CH{sub 2} content and network defects on the elastic properties of organosilicate glasses

Journal Article Knaup, Jan M ; Department of Physics, Harvard University, Cambridge, Massachusetts 02138 ; Han, Li ; ... - Physical Review. B, Condensed Matter and Materials Physics

Organosilicate glasses (OSGs) are used as low-k intermetal dielectrics for advanced integrated circuits. In this application, the material must fulfill two conflicting requirements: It has to have low density to reduce the dielectric constant while being sufficiently mechanically stable to withstand thermomechanical and other stresses during subsequent steps of integrated circuit manufacture. Recent experimental advances in improving the mechanical and electrical properties of these materials have not yet been systematically studied theoretically at the ab initio level due to the large model sizes necessary to realistically describe amorphous materials. In this paper we employ the density-functional-based tight-binding method to achievemore »« less

Short-ranged structural rearrangement and enhancement of mechanical properties of organosilicate glasses induced by ultraviolet radiation

Journal Article Iacopi, F ; Travaly, Y ; Eyckens, B ; ... - Journal of Applied Physics

The short-ranged bonding structure of organosilicate glasses can vary to a great extent and is directly linked to the mechanical properties of the thin film material. The combined action of ultraviolet (UV) radiation and thermal activation is shown to generate a pronounced rearrangement in the bonding structure of thin organosilicate glass films involving no significant compositional change or film densification. Nuclear magnetic resonance spectroscopy indicates loss of -OH groups and an increase of the degree of cross-linking of the organosilicate matrix for UV-treated films. Fourier transform infrared spectroscopy shows a pronounced enhancement of the Si-O-Si network bond structure, indicating themore »« less

Effects of plasma and vacuum-ultraviolet exposure on the mechanical properties of low-k porous organosilicate glass

Journal Article Guo, X. ; Shohet, J. L. ; Jakes, J. E. ; ... - Journal of Applied Physics

The effects of plasma exposure and vacuum-ultraviolet (VUV) irradiation on the mechanical properties of low-k porous organosilicate glass (SiCOH) dielectric films were investigated. Nanoindentation measurements were made on SiCOH films before and after exposure to an electron-cyclotron-resonance plasma or a monochromatic synchrotron VUV beam, to determine the changes of film hardness, elastic modulus, and crack threshold due to these exposures. This permits the effects of ion bombardment and photon bombardment to be analyzed separately. The role of energetic ions was examined with a variety of inert plasma-exposure conditions. The role of VUV photons was analyzed as a function of synchrotronmore »« less
