Are polymers advanced materials?
The advanced polymer composite essentially consists of two component materials: (i) the matrix material or polymer, which is generally the low-strength and low-modulus component and (ii) the fibre, which is the relatively high-strength and high-modulus component.
How are polymers used in medicine?
Their role as suture materials, tissue adhesives, and vascular grafts, materials for cosmetic implants, dental composites, contact and intraocular lenses, etc. The use of polymers in medicine is innumerable. orthopedic devices.
How are polymers used in agriculture?
Smart polymeric materials and smart delivery systems helped the agricultural industry to combat viruses and other crop pathogens, functionalized polymers were used to increase the efficiency of pesticides and herbicides, allowing lower doses to be used and to indirectly protect the environment through filters or …
What are the current advancement of polymer technology?
Scientists at the University of Manitoba have developed a new way to create mechanically stable, conductive polymer hydrogels. A chitosan (DCh-PPy) polymerizes acrylic acid using iron atoms to create a double-network hydrogel; the iron also contributes to exceptional self-healing properties.
What is the progress of polymer technology?
The recent developments of Polymer Technology have revolutionized the field of material science increasing the use of polymer based substances from building materials to Packing materials, Fancy decoration articles, Electrical engineering, Communications, Automobile, Aircrafts, etc.
What are medical polymers?
Medical polymers are utilized for a variety of human contact and non-contact applications in the medical industry. These materials are chiefly used in the manufacture of medical implants, devices, disposables (gloves, vials, tools), and packaging.
What is super absorbent polymer made of?
acrylic acid
How are superabsorbent polymers made. The main ingredients are acrylic acid, sodium hydroxide (or a similar neutralizing agent) and water plus a cross linker which forms the bridge that links one polymer chain to another.
What are the main factors that improve performance of polymers for controlling soil erosion?
such as organic carbon [11,12], porosity [13], soil texture [14,15], bulk density [16], and aggregate stability [17] have been found to be factors in controlling soil erosion.
