Smart rubber will recover its original mechanical strength within several hours of being split and then subsequently recombined. Residual hydrogen bond donors and acceptors responsible for the self-healing properties of the elastomer remain unpaired until the newly exposed surface comes in contact with another complementary surface, allowing formation of new intermolecular hydrogen bonds.
Silver-colored Silly Putty. Silly Putty is a toy containing silicone polymers that have unusual physical properties. It can flow like a liquid, bounce and can be stretched or broken depending on the amount of physical stress to which it is subjected.
Although the most common types of self-healing materials are polymers or elastomers, self-healing covers all classes of materials, including metals, ceramics, and cementitious materials. Healing mechanisms vary from an instrinsic repair of the material to the addition of a repair agent contained in a microscopic vessel.
Self-healing hydrogels are a specialized type of polymer hydrogel.A hydrogel is a macromolecular polymer gel constructed of a network of crosslinked polymer chains. Hydrogels are synthesized from hydrophilic monomers by either chain or step growth, along with a functional crosslinker to promote network formation.
Self-amalgamating tape is a non-tacky silicone rubber tape that when stretched and wrapped around cables, electrical joints, hoses, and pipes combines or unites itself into a strong, seamless, rubbery, waterproof, and electrically insulating layer. [1] [2] Unlike many other polymers and fibers, it is heat-, sunlight-, and weather-resistant.
The Grinberg Method is a method of teaching that focuses on using the body, [1] specifically body attention, perception and the individual's direct personal experience. The goal is for people to learn to be attentive to themselves and their surroundings, and stop automatic limiting habits in order to increase their ability to recuperate, and attain personal goals and well-being.
During the 2000s and onwards, fuse beads gained new popularity through online communities focused on using them to recreate pixel art sprites from video games. [ 4 ] [ 11 ] In 2015, a 4.65 m × 8.70 m fuse-bead picture was created from 1,680,200 beads in Väringaskolan, Sweden , and hung in Stockholm Arlanda Airport .
The fulcrum is an inflatable rubber ball. The fulcrum is a solid urethane ball. A sphere, either an inflatable rubber ball (such as a basketball) or a solid polyurethane ball, is the fulcrum on which the board is balanced, and the fulcrum is kept contained under the board by a guard rail or ring on the underside. By redistributing his/her ...
