US Patent:

20020083858, Jul 4, 2002
Filed:

May 15, 2001
Appl. No.:

09/858154
Inventors:

Alan MacDiarmid - Drexel Hill PA, US
Dirk Hohnholz - Philadelphia PA, US
Hidenori Okuzaki - Yamanashi, JP
International Classification:

B41F001/54
B41L047/56
B41L039/00
B41F033/00
US Classification:

101/484000
Abstract:

A method of forming a pattern of a functional material on a substrate is disclosed. In accordance with the method, a first pattern of a first material is applied to the substrate and a second functional material is applied to the substrate and the first material. The first material, the second functional material, and the substrate interact to spontaneously form a second pattern of the second functional material on the substrate. The invention is directed to methods for spontaneous pattern formation of functional materials on substrates, and devices produced according to the methods of the invention. In particular, the methods of the invention provide a simple, inexpensive method for patterning a functional material on a substrate, with broad applicability to numerous devices.

International Classification:

C08L 71/02
C08F 226/06
C08F 228/06
B29C 47/00
US Classification:

264465, 525187, 526258, 526256
Abstract:

US Patent:

55191118, May 21, 1996
Filed:

Nov 15, 1994
Appl. No.:

8/232236
Inventors:

Alan G. MacDiarmid - Drexel Hill PA
Sanjeev K. Manohar - Cincinnati OH
Luis H. C. Mattoso - San Carlos, BR
Assignee:

The Trustees of the University of Pennsylvania - Philadelphia PA
International Classification:

C08G 7300
US Classification:

528422
Abstract:

High molecular weight polyanilines are provided, alone with synthetic methods therefor. The methods generally comprise mixing aniline, protonic acid, salt, and a polymerization agent at the desired reaction temperature. The presence or the salt increases the molecular weight of the polyaniline produced. The reaction temperature is preferably maintained at lower temperatures to also increase the molecular weight of the polyaniline.

Assignee:

University Patents, Inc. - Norwalk CT
International Classification:

H01L 2928
US Classification:

357 8
Abstract:

Electrically conducting organic polymeric film material exhibiting a preselected room temperature n-type electrical conductivity ranging from that characteristic of semiconductor behavior to that characteristic of metallic behavior, is prepared by controlled electron donor doping of a polycrystalline film of polyacetylene with a metal dopant whose Pauling electronegativity value is no greater than 1. 6. Preferred metal dopants are the alkali metals. The procedure may be employed in preparing polyacetylene film with a p-n junction formed by two adjacent portions of the film respectively provided wth p-type and n-type electrical conductivities.
