Linear polymers consist of natural polymers such as collagen, gelatin, chitosan, hyaluronic acid, and synthetic polymers such as polylactic acid, poly(lactic-co-glycolic acid), polycaprolactone, and polyanhydrides. However, the development of bone implants that perform perfectly is still ongoing.
12 paź 2023 · Natural polymers can consist of inorganic or organic units. Some examples of plant-derived natural polymers are starch, cellulose, pectin, zein, pea, and soya. Common animal-based...
1 dzień temu · We start presenting an overview on recent applications of linear polymers and networks in condensed matter physics, chemistry and biology by briefly discussing selected papers (published within 2022–2024) in some detail. They are organized into three main subsections: polymers in physics (further subdivided into simulations of coarse-grained models and structural properties of materials ...
Polymerization is a chemical reaction that involves the formation of long-chain molecules known as polymers from smaller units called monomers. Polymerization reaction occurs when multiple monomers chemically bond together, forming large, complex structures. The polymerization process can be either natural or artificial.
The polymerization occurs by initial metathesis of the more highly strained double bond in the bicyclo[2.2.1]heptane part of the molecule (Section 4.9) to give a linear polymer, followed by cross-linking of different chains in a second metathesis of the remaining cyclopentene double bond.
Natural polymers: cellulose and DNA, versatile and vital in nature. Cellulose: from tree bark to flexible paper. DNA: natural polymer carrying genetic information, with complex functionality. Synthetic polymers: nylon and polyethylene, engineered for specific uses. Nylon: strong and versatile, revolutionizing textiles and beyond.
23 lis 2018 · Here we investigate a series of linear conjugated polymers with external quantum efficiencies for hydrogen production between 0.4 and 11.6%. We monitor the generation of the photoactive species...
