Hydroxyl-triggered fluorescence for location of inorganic materials in polymer-matrix composites

Hydroxyl-triggered fluorescence for location of inorganic materials in polymer-matrix composites† †Electronic supplementary information (ESI) available: Detailed experimental materials, apparatus, experimental procedures and characterization data. See DOI: 10.1039/c7sc03897f

There is a long-standing challenge to realize in situ visualization of incorporated inorganic materials in organic–inorganic composites in a post-labeling manner, owing to the lack of specific fluorescent organic dye molecules for targeting inorganic materials. Herein, we observe that the specific covalent B–O binding between the hydroxyl groups of inorganic materials and commercially available...

Metal- and Polymer-Matrix Composites: Functional Lightweight Materials for High-Performance Structures

The special topic ‘‘Metaland Polymer-Matrix Composites’’ is intended to capture the state of the art in the research and practice of functional composites. The current set of articles related to metal-matrix composites includes reviews on functionalities such as self-healing, self-lubricating, and selfcleaning capabilities; research results on a variety of aluminum-matrix composites; and invest...

A micromechanics approach for damage modeling of polymer matrix composites

A new model for damage evolution in polymer matrix composites is presented. The model is based on a combination of two constituent-level models an9 an interphase model. This approach reduces the number of empirical parameters ·since the two constituent level models are formulated for isotropic materials, namely fiber and matrix. Decomposition of the state variables down to the micro-scale is ac...

Aspect Ratio Requirements for Nanotube-Reinforced, Polymer-Matrix Composites

A fiber’s efficiency in a short-fiber composite can be accurately solved by shear-lag methods, which can account for fiber geometry, an imperfect interface (or interphase), and extend to low volume fractions. Such an analysis was used to evaluate the aspect ratio requirements for singlewalled nanotubes (SWNT) in a polymeric composite and contrast it to conventional fibers. The aspect ratio requ...
