Thermally degradable thermosetting materials

Degradable polyethylene nanocomposites with silica, silicate and thermally reduced graphene using oxo-degradable pro-oxidant

Polyethylene nanocomposites with silica, alumino-silicate and thermally reduced graphene were generated by adding pro-oxidant additive. Additive resulted in early degradation of pure polymer, however, the degradation was delayed in the presence of fillers. Graphene resulted in maximum extent of enhancement of peak degradation temperature (13-14 °C depending on the additive content) followed by ...

Nature or petrochemistry?-biologically degradable materials.

Naturally occurring polymers have been utilized for a long time as materials, however, their application as plastics has been restricted because of their limited thermoplastic processability. Recently, the microbial synthesis of polyesters directly from carbohydrate sources has attracted considerable attention. The industrial-scale production of poly(lactic acid) from lactic acid generated by f...

Degradable polymeric materials for osteosynthesis: tutorial.

This report summarizes the state of the art and recent developments and advances in the use of degradable polymers devices for osteosynthesis. The current generation of biodegradable polymeric implants for bone repair utilising designs copied from metal implants, originates from the concept that devices should be supportive and as "inert" substitute to bone tissue. Today degradable polymeric de...

Polyacylurethanes as Novel Degradable Cell Carrier Materials for Tissue Engineering

Polycaprolactone (PCL) polyester and segmented aliphatic polyester urethanes based on PCL soft segment have been thoroughly investigated as biodegradable scaffolds for tissue engineering. Although proven beneficial as long term implants, these materials degrade very slowly and are therefore not suitable in applications in which scaffold support is needed for a shorter time. A recently developed...
