Sacrificial Mechanical Bond is as Effective as a Sacrificial Covalent Bond in Increasing Cross-Linked Polymer Toughness

open access: yesJournal of the American Chemical Society, 2023
Sacrificial chemical bonds have been used effectively to increase the toughness of elastomers because such bonds dissociate at forces significantly below the fracture limit of the primary load-bearing bonds, thereby dissipating local stress. This approach owes much of its success to the ability to adjust the threshold force at which the sacrificial ...

Precision enhanced alignment bonding technique with sacrificial strategy

open access: yesFrontiers in Bioengineering and Biotechnology, 2023
This work proposes an “N2-1” sacrificial strategy to help to improve the accuracy of the bonding technique from the existing level. The target micropattern is copied N2 times, and (N2-1) of them are sacrificed to obtain the most accurate alignment.

Sacrificial adhesive bonding: a powerful method for fabrication of glass microchips [PDF]

open access: yesScientific Reports, 2015
AbstractA new protocol for fabrication of glass microchips is addressed in this research paper. Initially, the method involves the use of an uncured SU-8 intermediate to seal two glass slides irreversibly as in conventional adhesive bonding-based approaches. Subsequently, an additional step removes the adhesive layer from the channels. This step relies
