Publication number: 20230257641Abstract: A thermally conductive phase-change composition includes a mixture of 5 to 25 weight percent thermoplastic polymer; 20 to 45 weight percent phase-change material; and 30 to 65 weight percent thermally conductive particles, wherein weight percent is based on the total weight of the composition and totals 100 weight percent, and wherein thermal conductivity of the composition is at least 3.0 W/m-K at a temperature below the transition temperature of the phase change material and thermal conductivity of the composition is at least 2.0 W/m-K at a temperature above the transition temperature of the phase change material, wherein thermal conductivity is determined in accordance with ASTM E1530. The phase-change compositions are reworkable and can be easily and cleanly removed from a device for maintenance and repair and repositioned without causing damage to the device.Type: ApplicationFiled: July 15, 2021Publication date: August 17, 2023Inventors: Kuitian Tan, David William Baker, Ian Smith

Patent number: 11021559Abstract: Disclosed herein is a process for laminating a polar substrate with a film cast from a sulfonated block copolymer having at least one end block A and at least one interior block B wherein each A block contains essentially no sulfonic acid or sulfonate ester functional groups and each B block is a polymer block containing from about 10 to about 100 mol percent sulfonic acid or sulfonate ester functional groups based on the number of monomer units. The film is exposed to water and dried onto a polar or active metal substrate. The laminates do not delaminate in the presence of water, or in a humidity of up to 85%, and at a temperature of at least 60° C. The laminates are used for a variety of applications including energy exchange applications.Type: GrantFiled: November 8, 2019Date of Patent: June 1, 2021Assignee: Kraton Polymers LLCInventors: Kuitian Tan, Carl L Willis, Steven Huynh
