Patent number: 12552921Abstract: Provided are films made from polymer blends including post-consumer resin (PCR). The films are formed from a polymer blend that includes a PCR, a low density polyethylene and/or ethylene/carbon monoxide copolymer (ECO copolymer), and a modification agent. The films, which include a PCR, contribute to improved sustainability and in aspects maintain or minimize the reduction of desirable properties, such as elastic recovery.Type: GrantFiled: April 7, 2021Date of Patent: February 17, 2026Assignee: Dow Global Technologies LLCInventors: Rajen M. Patel, Carol L. Tsai, Daniel G. Abebe, Yongchao Zeng, Teresa P. Karjala, Xiaofei Sun, Jessica L. Rogers, Francis O. Olajide, Jr.

Publication number: 20250163235Abstract: Articles useful for bedding and other comfort applications include a coated polyurethane foam. The coating includes an elastomeric polymer, a phase change material, a non-encapsulated wax and optionally a hydrophilic polymer. The coating provides desirable haptic properties, including a “cool touch” feature that creates a sensation of coolness when touched, and a highly smooth surface.Type: ApplicationFiled: February 28, 2023Publication date: May 22, 2025Inventors: Yasmin N. Srivastava, Thomas C. Fitzgibbons, Praveenkumar Boopalachandran, Daniel G. Abebe, Tian Lan, Yu Xindi

Patent number: 11878088Abstract: The invention includes chitosan nanofibers having enhanced structural integrity, compositions comprising such chitosan nanofibers, and related methods of use. In a particular aspect, electrospun chitosan nanofibers can be reversibly acylated to enhance structural integrity and promote healing and the formation of tissues in a subject. In another aspect, electrospun chitosan nanofibers comprising at least a portion of the amino groups protected, such as through N-tert-butoxycarbonyl groups, demonstrate enhanced structural integrity and promote healing and the formation of tissues in a subject. The invention also includes compositions and methods for producing a modified chitosan material having anti-inflammatory and pro-healing characteristics and methods of using the modified chitosan materials in a film, a gel, a membrane, microfibers, nanofibers, nano- or micro-particles/spheres and/or sponges. In some aspects, microspheres and methods of producing microspheres comprising modified chitosan are included.Type: GrantFiled: December 1, 2021Date of Patent: January 23, 2024Assignee: The University of Memphis Research FoundationInventors: Joel D. Bumgardner, Hengjie Su, Tomoko Fujiwara, Daniel G. Abebe, Kwei-Yu Liu
