Xerographic properties were measured for vitreous bismuth-selenium films prepared by flash evaporation techniques in the 0-3 at. % Bi range. Optimum sensitivity was observed in the 1.1 at. % Bi region with broad, relatively flat spectral response fro

A new method is described for bonding gold to Teflon FEP, yielding high joint strength without affecting the electrical properties of the virgin polymer material. The method consists of depositing a 1000-A aluminum layer onto the Teflon by evaporatio

Heterogeneous nucleation and crystallization of FEP Teflon and nylon 6 melts against high energy surfaces (i.e., gold) produce an interfacial region, in these polymers, of high mechanical strength. Dissolution of the metal substrate rather than remov

Exposure of polyethylene film to UV radiation at wavelengths of ≤2537 A is sufficient to induce surface crosslinking and to facilitate the formation of strong adhesive joints to these surfaces with conventional adhesives. Reduction of the vapor pre

Nucleation and crystallization of polytetrafluoroethylene in contact with gold produces a surface region of high mechanical strength in the polymer as evidenced from the strong adhesive joints prepared with a conventional epoxy adhesive. In addition,

In this paper we examine how the joint strength of lap joints containing a brittle adhesive may be affected by partial removal of adhesive from the bonded area. It is found that the shear strength in tension of a lap joint specimen is governed essent

The CASING (crosslinking by activated species of inert gases) treatment of polypropylene film in both oxygen and nitrous oxide is shown to be an effective surface treatment for conventional adhesive bonding. A crosslinked surface extending to a depth

The morphological character of the surface region of polyethylene has been considered with respect to adhesion and adhesive joint strength. By melting polyethylene onto a high-energy surface (e.g., aluminum) we have provided for extensive nucleation
