This talk will cover two classes of electroactive polymers under development recent at Penn State. One is the modified poly(vinylidene fluoride-trifluoroethylene) (P(VDF-TrFE)) polymer and the other is the high dielectric constant all-organic composite. Recently, making use of the defect structure modification in P(VDF-TrFE) based polymers, we converted normal ferroelectric P(VDF-TrFE) into rel...

Low-density porous aramid films using inexpensive and widely available polymers as porosity promoters, that is, polyvinyl alcohol (PVA), poly(2-ethyl-2-oxazoline) (PEOx), cellulose polyacetate (CA) were fabricated. Porous poly (m-phenylene isophthalamide) obtained by the standard casting procedure mixtures of with either PVA, PEOx, or CA, followed removal promoter immersing them in water aceton...

High-performance polymers are an important class of materials that used in challenging conditions, such as aerospace applications. Until now, 3D printing based on stereolithography processes can not be performed due to a lack suitable materials. There is report new and compositions enable objects having extremely high thermal resistance, with Tg 283 °C excellent mechanical properties. The by lo...
