In this work, we present the synthesis of an alternative precursor for chemical vapour deposition of parylene AF-4 to the widely used standard, octafluoro[2.2]paracyclophane. The standard precursor suffers from uncertainties in its supply chain and i

Recent advances in photonic crystals have enabled high-efficiency thermophotovoltaic (TPV) energy conversion by allowing near-perfect spectral control. In this paper, photonic crystals fabricated in thick tantalum (Ta) coatings, sputtered onto a meta

The aim of this paper was to test the thermal and environmental stability of poly(4-ethynyl-p-xylylene-co-p-xylylene) thin films prepared by chemical vapor deposition (CVD) and to optimize the reaction conditions of the polymer. Fourier transformed i

A method is presented to polymerize inexpensive and readily available electron-rich monomers via oxidative chemical vapor deposition. The process uses benzoyl peroxide, an organic oxidant, flash evaporated from a chloroform solution via direct liquid

Two cross-linkable parylene polymers, tert-butylethynyl and phenylethynyl, were deposited via the well-known Gorham method from a unique synthesis route to their respective cyclophane precursors. Unlike the bulky substituent group-functionalized pary

The Achilles heel of the parylene polymers is their oxidative stability at room temperature with UV exposure and at elevated temperature >115 °C in air. This weakness is attributed to the aliphatic carbon-carbon single bond in the main-chain backbon

The parylene CVD platform is a unique one since it enables the room temperature deposition of high-performance polymers from the resonance-stabilization of the p-xylylene intermediate. This intermediate, or the derivatives of it, have the same stabil
