The majority of studies on OS were performed with DHPs with various lipophilicity, but only a few studies reported amphiphilicity of DHP derivatives.
For instance it has been reported that PAON is not antibacterial but becomes membrane-disruptive and bactericidal when one modulates the amphiphilicity of PAON via the incorporation of nonpolar units.
Lipid modification of the 17-kilodalton membrane immunogen of Treponema pallidum determines macrophage activation as well as amphiphilicity.
There is also disclosed a method to identify and optimize the facial amphiphilicity of polyamide, polyester, polyurea, polyurethane, polycarbonate and polyphenylene polymers.
It is thought that the compatibilizer amphiphilicity is the key factor that influences the membrane ability to induce either high compaction and less free volume (upon maximized compatibilization) or the reverse upon minimized compatibilization which dominates the performance [20], The major advantage of such membranes is their high mechanical properties which may allow for extended use without affection of their performance.
This raises the amphiphilicity extent as the sole factor that influences the characteristics of the resulting nanovulcanizaies.
We report herein observation of a novel self-assembly of [pi]-conjugated polymers having amphiphilicity induced by protonation of nonamphiphilic polymers in solution.
