SYSTEMS AND METHODS FOR CONTROLLING THE DEGRADATION OF DEGRADABLE MATERIALS

摘要

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.

1. A system, comprising:
a substrate including a degradable material, the degradable material configured to substantially degrade over a first time period; and a barrier including at least one of a conformal coating and a liquid impregnated surface, the barrier configured to control a degradation profile of the degradable material such that the degradable material substantially degrades over a second time period.
