Keyword: "frost resistance" - PubAg Search Results

sensor is developed by introducing zwitterionic proline (ZP) into gellan gum/polyacrylamide (GG/PAAm) double network (DN) hydrogel. The existence of ZP endows the hydrogel with remarkable frost resistance. The toughness and transparency of zwitterionic Ca-GG/PAAm-ZP DN hydrogel can be maintained down to −40 °C.

The polymer in an embodiment can be polyacrylamide (PAM) which can be partially hydrolyzed to introduce cross-linking sites, or may be hydrolysable at the elevated temperatures seen in subterranean formations. The polymer may be cationic to facilitate acid solubility and stability. In another embodiment the polymer is amphoteric or zwitterionic.
