Biodegradability morphological test

In the aquatic arena some of the biodegradation tests are done with volumes of less than a liter. Tests to evaluate community interaction conducted in a laboratory have test vessels ranging in size from 1-1 to 55-gal aquariums. Larger test systems can also be used outside the laboratory. A proposed outdoor aquatic microcosm proposal uses large tanks of approximately 800-1 capacities. Larger still are the pond mesocosms used for pesticide evaluations. These systems are designed to mimic farm ponds in size and morphology.

Campos et al. [21] studied sisal flber-reinforced TPS and polycaprolactone, both biodegradable pol5miers. Sisal fibers (5% and 10%) were extruded in a twin-screw extruder with TPS/ polycaprolactone (80 20 wt). Films were produced with a single extruder and analyzed by field emission gun scanning electron microscopy, mechanical tests, thermogravimetric analysis, and differential scanning calorimetry. The morphology of the composites with 10% sisal fiber content presented an interface...
