Apr 7, 1999
Appl. No.:
09/287978
Inventors:
Lawrence T. Drzal - Okemos MI
Narasimharao Dontula - Rochester NY
Richard L. Schalek - Haslett MI
Alekh S. Bhurke - East Lansing MI
Michael J. Rich - Williamston MI
Laura M. Fisher - East Lansing MI
Ming Xie - Norton Shores MI
Assignee:
Board of Trustees of Michigan State University - East Lansing MI
International Classification:
C08F 246
US Classification:
427487, 427457, 427492, 427556, 4273981
Abstract:
A method using irradiation with optical light having a wavelength of 160 to 500 nanometers without higher wavelengths with cooling of the surface during the irradiation to modify the surface ( A, A, A, A, A, A) of a substrate ( ) is described. The light is filtered or the lamp ( ) is restricted to the limited range to avoid the affects of the higher spectra. The light can be pulsed or continuous. The method is significantly enhanced by the presence of water ( ) on the surface, preferably also in the presence of ozone in the water. The treated surfaces are more paintable and bondable.

US Patent:
6551407, Apr 22, 2003
Filed:
Jan 15, 2001
Appl. No.:
09/761089
Inventors:
Lawrence T. Drzal - Okemos MI
Michael J. Rich - Williamston MI
Laura M. Fisher - Dearborn MI
Assignee:
Board of Trustees of Michigan State University - East Lansing MI
International Classification:
B08B 700
US Classification:
134 1, 264400, 264139
Abstract:
A method using irradiation of surfaces A of substrates ( ) with ultra violet light to remove a parting agent is described. The light can be pulsed or continuous. The treated surfaces are more paintable and bondable. The treated molds prevent the introduction of surface inhomogeneities caused by the parting agent.

Process For The Treatment Of A Fiber

View page
US Patent:
6648973, Nov 18, 2003
Filed:
Oct 22, 2002
Appl. No.:
10/277843
Inventors:
Lawrence T. Drzal - Okemos MI
Michael J. Rich - Williamston MI
Assignee:
Board of Trustees of Michigan State University - East Lansing MI
International Classification:
C23C 1600
US Classification:
118718, 118722, 118 67, 118 68, 1563455, 427534
Abstract:
A process using ultraviolet light having a wavelength of 160 to 500 nanometers without higher wavelengths and a high intensity between about 1 and 40 watts/cm to surface treat a carbon containing fiber is described. The treated fiber contains an enhanced amount of oxygen on the surface which significantly improves the bondability of the fiber in composites.

Epoxy Resin And Polyglycoside Based Polymers And Process For The Preparation Thereof

View page
US Patent:
6723802, Apr 20, 2004
Filed:
Aug 19, 2002
Appl. No.:
10/223266
Inventors:
Lawrence T. Drzal - Okemos MI
Seong Ok Han - Kyungki-do, KR
Assignee:
Board of Trustees of Michigan State University - East Lansing MI
International Classification:
C08K 304
US Classification:
525532, 523446, 523466, 523468
Abstract:
Epoxy resin polyglycoside-based cured polymers and process for the preparation are described. A particular epoxy resin precursor is the diglycidyl ether of bisphenol A. A particular glucose based polymer is a glucose malic acid ester-vinyl copolymer. The polymers have a degree of biodegradability because of the polyglycoside as well as elevated temperature stability and are useful in transportation vehicle settings. Natural source fillers, such as cellulose fibers, which are treated or untreated, exfoliated clays or exfoliated graphite can be used.

The polymeric material can include between about 30 to about 50 percent by weight polyvinyl chloride, polyethylene glycol, polyglycolide, ethylene vinyl acetate, polycarbonate, polycaprolactone, polyhydroxyalkanoates, or polyolefins modified with polar groups, for example, ionomers. The plasticizer is typically an epoxidized vegetable oil or esterified and epoxidized vegetable oil and is typically present in an amount of between about 10 and about 50% by weight. In some embodiments, the compatibilizer is a polyolefin modified with one or more polar functional groups, and is typically present in an amount of between about 5 and about 10% by weight. The material can be used in decorative surface coverings, such as a floor coverings, particularly when it is in the form of a polymeric sheet.
