Objective:In order that the adhesive character could be improved to modify the octyl-α-cyanoacrylate(OCA) medical adhesive.Methods:Suitable modifiers involving polycaprolactone(PCL),dibutyl phthalate (DBP),dioctyl phthalate(DOP) and poly octyl methacrylat(POMA) have been chosen to modify the OCA adhesive,then tensile shear strength and adhesive strength are tested to evaluate the bond character of adhesives.Results:The PCL group's tensile shear strength and adhesive strength in normal temperature are descended while the other groups'are all enhanced.Conclusion:The modification of properties of the other groups is effectively promoted in the aspect of the bond character,except the PCL group treated in normal temperature and the PCL modified group treated by rectification get a best improvement in the agglutinate intention, while the stability is expected to be improved. 展开更多

Hydrogels are a class of special materials that contain a large amount of water and behave like rubber.These materials have found broad applications in tissue engineering,cell culturing,regenerative medicine etc.Recently,the exploration of peptide-based supramolecular hydrogels has greatly expanded the repertoire of hydrogels suitable for biomedical applications.However,the mechanical properties of peptide-based hydrogels are intrinsically weak.Therefore,it is crucial to develop methods that can improve the mechanical stability of such peptide-based hydrogels.In this review,we explore the factors that determine or influence the mechanical stability of peptide-based hydrogels and summarize several key elements that may guide scientists to achieve mechanically improved hydrogels.In addition,we exemplified several methods that have been successfully developed to prepare hydrogels with enhanced mechanical stability.These mechanically strong peptide-based hydrogels may find broad applications as novel biomaterials.It is still challenging to engineer hydrogels in order to mimic the mechanical properties of biological tissues.More hydrogel materials with optimal mechanical properties suitable for various types of biological applications will be available in the near future. 展开更多
