Respuesta :
Two biodegradable polymers that could serve as an alternative to the currently employed poly(glycolic acid), poly(lactic acid), or polyhydroxy butyrate were given a thorough evaluation if one were looking for orthopedic applications. Three distinct grades of a new starch-based polymer and cellulose acetate were examined. Tensile and instrumented impact tests, rheological measurements, scanning electron microscopy, X-ray diffraction, Fourier transformed infrared spectroscopy, differential scanning calorimetry, and testing for long-term deterioration in Hank's solution were all part of the characterization. The findings demonstrate that both polymers, particularly the starch-based one, have a significant promise for biomedical applications that call for appropriate mechanical qualities coupled with a regulated disintegration rate.
What are biodegradable polymers?
Biopolymers are organic, biodegradable polymers. The most distinctive family of these natural polymers belongs to the polysaccharide class, which includes starch and cellulose. Proteins and other natural polymers can be combined to create biodegradable products. These two sources are the primary renewable ones for biopolymers.
