  • Patent number: 9120125
    Abstract: The present invention includes systems, methods and compositions for the encapsulation of particles. In one form, the system comprises one or more particles, a rotatable reaction chamber in a plasma enhanced chemical reactor to accept one or more particles, and at least one carbonaceous compound to be used in the rotatable reaction chamber, wherein the carbonaceous compound is polymerized onto a surface of one or more particles forming a polymer film encapsulating one or more particles. Using systems, methods, and compositions of the present invention, any particle encapsulated with a degradable or nondegradable polymer film may be introduced and/or released into an environment. The polymer film as well as introduction of encapsulated particles and release therefrom into an environment are controlled by the present invention.

  • Publication number: 20030113477
    Abstract: A device, and its production method, the device has a substrate and a coating composition, the coating composition being formed by the gas phase or plasma polymerization of a gas comprising at least one organic compound or monomer. The polymerization is carried out using a pulsed discharge having a duty cycle of less than about ⅕, in which the pulse-on time is less than about 100 msec and the pulse-off time is less than about 2000 msec. The duty cycle can also be varied, thus the coating composition can be gradient layered accordingly. The device has a coating composition which is uniform in thickness, pin-hole free, optically transparent in the visible region of the magnetic spectrum, permeable to oxygen, abrasive resistant, wettable and biologically non-fouling.
