An electrically-responsive infrared reflective device filled with positive liquid crystals, a chiral doping agent, a light absorbing agent and a polymer network. The light absorbing agent is capable of causing a gradient change in light intensity in the filled area irradiated by ultraviolet light, so that the concentration of the polymer network changes in a gradient, thereby forming a gradient of pitch of the positive liquid crystal helix structure. When a power supply voltage is applied, the long axis of the positive liquid crystal will rotate in a direction parallel to the electric field. Since the anchoring effect of the polymer network on the liquid crystals decreases with the decrease of the concentration of the polymer network, the pitch of the positive liquid crystals is gradually damaged, such that the infrared reflection bandwidth of the infrared reflective device gradually reduces from a long wavelength to 0 nm.

Liquid crystal polymers (LCPs) are described herein that include novel arrangements of bio-mimicking properties for use in surgery, therapy, and treatment of medical or comfort issues. Through the particular arrangements medical devices and portions of them may be adapted to have properties that dampen and dissipate vibrations such as shocks to body tissues during surgical recovery and/or during subsequent use. This dampening is attained by novel arrangements of LCP and processes for forming them that vary from prior attempts at synthesizing activated LCP elements. These novel arrangements include using LCP bodies that include thicknesses and properties that have not been demonstrated or achieved for medical or other purposes and that are achieved using distinct processes. These novel LCP arrangements and methods of creating them can produce medical devices that bio-mimic natural tissue or operation to provide better results for patients.

The present invention relates to a thermoplastic block copolymer comprising at least one PA block and at least one PB block. The PA block represents a polymer block comprising one or more units of monomer A, and the PB block represents a polymer block comprising one or more units of monomer B. Monomer A is a vinyl, acrylic, diolefin, nitrile, dinitrile, acrylonitrile monomer, a monomer with reactive functionality, or a crosslinking monomer. Monomer B is a radically polymerizable triglyceride or mixtures thereof, typically in the form of a plant or animal oil. The present invention also relates to a method of preparing a thermoplastic block copolymer or novel thermoplastic statistical copolymers by polymerizing a radically polymerizable monomer with a radically polymerizable triglyceride or mixtures thereof via reversible addition-fragmentation chain-transfer polymerization (RAFT), in the presence of an free radical initiator and a chain transfer agent.
