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. PDMS is particularly known for its unusual rheological (or flow) properties. It is optically clear and, in general, inert, non-toxic, and non-flammable. It is one of several types of silicone oil (polymerized siloxane). The applications of PDMS range from contact lenses and medical devices to elastomers; it is also present in shampoos (as it makes hair shiny and slippery), food (antifoaming agent), caulk, lubricants and heat-resistant tiles.

Fabrication of Highly Sensitive Porous PDMS Pressure Sensor through Control of Rheological Properties. Population aging is a notable global social phenomenon that is progressing rapidly. Currently, Japan, Finland and Italy have the highest percentages of elderly people. Within the Organization for Economic Co-operation and Development (OECD), Greece, Korea, Poland, Portugal, Slovenia, and Spain are noted for their accelerated aging rates. Outside the OECD, Brazil, China, and Saudi Arabia are among the countries experiencing the fastest aging rates. [1,2] Caring for this aging population has become a global priority, with a strong emphasis on cost-effectiveness. Pressure sensors are particul…

Self-Cross-Linking of Amine-Functionalized Polydimethylsiloxane on Metal Substrates with Humidity-Responsive Healing.. Polymer coatings require durability to maintain their protective and functional properties throughout their service life. This study presents amine-functionalized polydimethylsiloxane (PDMS) coatings that cross-link through metal substrate-catalyzed imine bond formation without additional curing agents. Amine-functionalized PDMS undergoes oxidative cross-linking on metal substrates, forming imine-linked networks with viscoelastic properties that are investigated as a function of curing time and temperature. The metal-catalyzed curing results in network formation across diff…

Decoupling parameters of adhesion from viscoelasticity in the human perception of stickiness <i>via</i> shear-stiffening elastomers.. In engineering, the adhesion or "tack" of an object can be related to its bulk material properties and interfacial adhesion, sometimes quantified by a peak adhesive force or work of adhesion. However, it is unknown how these engineering contributions to adhesion compare to the human perception of "stickiness". Here, to decouple between adhesive and viscoelastic parameters, we used shear-stiffening elastomers to modulate viscoelastic and adhesive contributions by velocity. Through psychophysical testing, we discovered that the human perception of "…

A silicone or polysiloxane is a polymer composed of repeating units of siloxane (−O−SiR2−O−SiR2−, where "R" stands for an organic group). They are typically colorless oils or rubber-like substances. Silicones are used in sealants, adhesives, lubricants, medicine, cooking utensils, thermal insulation, and electrical insulation. Some common forms include silicone oil, grease, rubber, resin, and caulk. From the chemical perspective, silicones are unusual because they feature inorganic backbones, composed only of Si and O, but they have properties of organic polymers. They represent one of the main applications of organosilicon chemistry. Silicone is often confused with one of its constituent e…
