Hydrogen-bond basic siloxane phosphonate polymers for surface acoustic wave (SAW) sensors

TL;DR: This work has shown that not only the geometry of the molecule but also the number of atoms in the molecule can vary greatly both in the stationary and the liquid phase of the reaction.

TL;DR: A critical review of the recent developments in nano- and micro-engineered synthetic recognition materials predominantly used for SAW-based organic vapor sensors is presented, highlighting their potential to realize real-time vapor sensing.

TL;DR: In this paper, the synthesis and characterization of a h-b acidic hyperbranched carbosilane fluoroalcohol based sorbent polymer (poly(methyldi(1,1, 1-trifluoro-2-trifioromethyl-2,hydroxypent-4-enyl)silane; HCSFA2), which is suitable for sorbing these hazardous H-b basic analytes is reported.

TL;DR: In this article, the use of electrospun nanofibrous film for surface acoustic wave (SAW) sensors to enhance its chemical detection capability was reported, which can not only offer more adsorption sites for vapor molecules, but also shortens the diffusion length of vapor molecules into polymer material.

TL;DR: In this article, the selection of sensor coatings for the complete sensor array is logically made through a systematic variation of the solubility properties of the coating materials, so that each sensor is selective for a different balance of solubilities interactions.

TL;DR: In this article, a series of novel hyperbranched hydrogen-bond acidic polymers for surface acoustic wave (SAW) sensor applications were prepared by functionalizing polycarbosiloxanes or poly carbosilanes with phenol or hexafluoro-2-propanol groups.

TL;DR: In this article, a method for estimating the responses of polymer-coated acoustic wave vapor sensors has been developed to construct linear solvation energy relationships that correlate partition coefficients on a given polymer with various solute solvation parameters.
