Publication number: 20090137044Abstract: The present invention relates to culturing cells utilizing a matrix of microfibrillated thermoplastic polymeric materials. More specifically, the present invention relates to a method of culturing cells. In addition, the invention relates to a biaxially oriented microfibrillated article for culturing cells dispersed in a cell culture medium. The matrix of thermoplastic polymeric materials for culturing cells of this invention finds use in tissue engineering and wound healing applications.Type: ApplicationFiled: February 3, 2009Publication date: May 28, 2009Inventors: Mario A. Perez, Terry R. Hobbs, Stephanie J. Moeller

Patent number: 7014803Abstract: A composite formed of a polymer matrix phase having a reinforcement phase including polymeric microfibers. The microfibers are preferably formed of a highly oriented polymer, having a high modulus value and a large surface area. The large surface area can serve to tightly bind the microfibers to the polymer matrix phase. The microfibers can be provided as a fully- or partially-microfibrillated film, as a non-woven web of entangled microfibers, or as a pulp having free fibers. The microfibers can be embedded in, or impregnated with, a polymer or polymer precursor. Some composite articles are formed from thermoset resins cured about a highly oriented polypropylene microfiber reinforcement phase, providing a strong, tough, moisture resistant article. One composite includes a matrix and reinforcement formed of the same material type and having substantially equal refractive indices, allowing the composite to be optically clear.Type: GrantFiled: July 14, 2003Date of Patent: March 21, 2006Assignee: 3M Innovative Properties CompanyInventors: Mario A. Perez, Michael D. Swan, Terry R. Hobbs, Allen R. Siedle

Patent number: 6890649Abstract: The present invention relates to aliphatic polyester microfibers, films having a microfibrillated surface, and methods of making the same. Microfibers of the invention can be prepared by imparting fluid energy, typically in the form of high-pressure water jets, to a highly oriented, highly crystalline, aliphatic polyester film to liberate microfibers therefrom. Microfibrillated films of the invention find use as tape backings, filters for particulate contaminants, such as face masks and water or air filters, fibrous mats, such as those used for removal of oil from water and those used as wipes, and thermal and acoustical insulation. Microfibers of the invention, when removed from the film matrix may be used in the preparation of woven or nonwoven articles and used as wipes for the removal of debris or dust from a surface. The microfibers and microfibrillated articles of the invention may be biodegradable, rendering them useful for geotextiles.Type: GrantFiled: August 25, 2003Date of Patent: May 10, 2005Assignee: 3M Innovative Properties CompanyInventors: Terry R. Hobbs, Philip P. Soo, Mario A. Perez, Christopher K. Haas, Robert S. Kody

Publication number: 20040213928Abstract: A receptor medium with an oriented film having at least one microfibrillated surface is described. The receptor medium can receive jettable materials, which include inks, adhesives, particulate dispersions, electrically, thermally or magnetically modifiable materials, biological fluids, chemical reagents and combinations thereof. The microfibrillated surface provides good ink receptive properties particularly for solvent based inks.Type: ApplicationFiled: May 14, 2004Publication date: October 28, 2004Applicant: 3M Innovative Properties CompanyInventors: John M. Sebastian, Jeffrey O. Emslander, Mario A. Perez, Terry R. Hobbs, Robert S. Kody, Caroline M. Ylitalo, Robert D. Taylor, Oh Sang Woo
