A new cross-linking route via the unusual collision kinematics of hyperthermal protons in unsaturated hydrocarbons: the case of poly(trans-isoprene)†
Abstract
The bombardment of a ∼18 nm film of poly(trans-isoprene) molecules (∼300 000 carbon atoms per molecule) with a mass-separated C bonds. The method produces ultrathin polymeric films via cross-linking with a dry process having high chemical selectivity and reactivity but requiring no thermal cost and no chemical additives, conditions that are commonly required in the fabrication of microelectronics and photonics.
