Hybrid nanopaper of cellulose nanofibrils and PET microfibers with high tear resistance

摘要

Tear resistance = force required to propagate a tear for a defined distance For fiber networks tear resistance increases with 1. fiber length 2. fiber strength 3. fiber-fiber bond strength 4. number of bonds Nanopaper have low tear resistance compared to regular paper 1. Fibrils shorter than fibers 2. Individual fibrils weak absolute strength - break 3. Dense material.
