Polydimethylsiloxane (PDMS), also known as dimethylpolysiloxane or dimethicone, is a silicone polymer with a wide variety of uses, from cosmetics to industrial lubrication and passive daytime radiative cooling. [1] [2] [3] PDMS is particularly known for its unusual rheological (or flow) properties.
Polydimethylsiloxane (PDMS) is a typical release agent. A release agent (also mold release agent, release coating, or mold release coating) is a chemical used to prevent other materials from bonding to surfaces. Release agents aid in processes involving mold release, die-cast release, plastic release, adhesive release, and tire and web release. [1]
The transfer of the SAMs is a complex diffusion process that depends on the type of molecule, concentration, duration of contact, and pressure applied. Typical stamps use PDMS because its elastomeric properties, E = 1.8 MPa, allow it to fit the contour of micro surfaces and its low surface energy, γ = 21.6 dyn/cm².
A composite, thin PDMS stamp with a rigid back support has been used for patterning to help solve this problem. Magnetic field assisted micro contact printing: to apply a homogeneous pressure during the printing step, a magnetic force is used. For that, the stamp is sensitive to a magnetic field by injecting iron powder into a second layer of PDMS.
PDMS (Plant Design Management System) as it is known in the 3D CAD industry, is a customizable, multi-user and multi-discipline, engineer controlled design software package for engineering, design and construction projects in offshore and onshore.
A process driven messaging service (PDMS) is a service that is process oriented and exchanges messages/data calls. A PDMS is a service where jobs and triggers can be put together to create a workflow for a message. Messaging platforms are considered key Internet infrastructure elements [by whom?]. A concept that once mainly encompassed email ...

PDMS stamps are pieces of polydimethylsiloxane (PDMS), a silicone, that have been patterned usually against a master mold to form a relief pattern used in soft lithography. This PDMS stamp can be used in either its current form as a relief surface for techniques such as microcontact printing or can also be attached to an external source by ...
