Recently in 2012, the researchers in NIMTE developed a novel route to make PI bead foams using a mixed physical blowing agent. By increasing the gas solubility in PI matrix and improving cell nucleation, they have successfully developed the PI foaming technology. The resultant PI bead foams present high expansion ratio of 50-60 times and well-defined cell morphology.  

At present, composite materials research team of the Ningbo Institute of Materials Technology &Engineering, CAS achieves a research progressin the high thermal conductivity of thermoplastic matrix composites. The high thermal conductivity composites of nylon 6 resin matrix were developed by the twin-screw extruder. 

NIMTE,CAS has developed an innovative and convenient method for improving carbon fiber composites interfacial properties by means of directly introducing graphene oxide (GO) sheets dispersed in the fiber sizing onto the surfaces of individual carbon fibers.

Recently, Prof. Runwei Li and his co-workers used superconducting niobium (Nb) as the anode element and fabricated the Nb/ZnO/Pt sandwich structured device, through dedicated design and operation, they observed superconducting behavior of the filaments at low temperatures and also conductance quantization behaviors of the atomic scale filaments at room temperature. 

Thus,mullite fiber plays a key role in the national economy development and is an important element to improve industries’energy efficiency.
One of the most important challenges in manufacture of mullite fiber is to control the porosity which may lead to fracture and low strength of fibers.
At present,the group has made a progress to reduce the porosity and improve the stre...
