Both poly(vinylidene fluoride) (PVF 2 ) and nylon 11 are ferroelectric polymers, and have been extensively studied over the past two decades. Blend films were made from mixed powders of these two polymers, which were then melt pressed and cold drawn.

The ferroelectric properties of unoriented films of a random copolymer of vinylidene fluoride with trifluoroethylene (73/27 mol %) as a function of plasticizer concentration, tricresyl phosphate (TCP), were examined. The percentages of dopant chosen

It is known that melt-quenched, cold-drawn, and then annealed nylon 11 films possess a particular doubly oriented hydrogen-bonded sheet structure: the hydrogen-bonded sheets being in the plane of the film and the molecular chain direction being in th

Measurements of the high frequency dielectric and thickness-mode electromechanical properties of ferroelectric nylon 11 are reported. Two sets of nylon 11 film samples were produced. The first set was melt-quenched and poled, while the second set was

Following studies of the ferroelectric behavior of the odd-numbered nylons, the ferroelectric switching mechanisms have been investigated in terms of the crystal orientation or reorientation using wide angle X-ray diffraction method. It has been foun

The ferroelectric and piezoelectric properties of a new class of polymer ferroelectric and piezoelectric materials, nylon 11/polyvinylidene fluoride (PVF2) bilaminate films, prepared by a co-melt-pressing method, is presented. The bilaminate films ex
