Presented herein are articles and methods featuring substrates with thin, uniform polymeric films grafted (e.g., covalently bonded) thereupon. The resulting coating provides significant reductions in thermal resistance, drop shedding size, and degradation rate during dropwise condensation of steam compared to existing coatings. Surfaces that promote dropwise shedding of low-surface tension condensates, such as liquid hydrocarbons, are also demonstrated herein.

Embodiments described herein relate generally to a system and methods for controlling and/or modifying the degradation behavior of degradable materials via a surface treatment and/or coating. This surface treatment and/or coating (also referred to herein as a “barrier”) can be used to modify the degradation profile without changing the bulk of the degradable material. The system includes a substrate that includes a degradable material and barrier configured to protect the substrate from a foreign environment. The barrier can include a conformal coating and/or a liquid impregnated surface engineered specifically to tailor the degradation profile of the underlying substrate. Optionally, a trigger mechanism can be used to further control and/or modify the degradation behavior of the substrate.

A downhole tool has a substrate including a degradable material, a protective barrier configured to protect the degradable material from a downhole environment, and a first trigger comprising a first trigger material that delaminates after contact with an organic solvent.
