A series of new polymer, polyepichlorohydrin (PECH)-triazole polymer with side chain with different number of methylene groups, were synthesized to prove this proposal. The newly synthesized polymer has high film-formation capacity and no halogens. The interactions between ether oxygen and imine nitrogen atoms depress the dipole effects and the hydrophobic interactions between extended methylene groups of the side chain on triazole compact the molecular volume, so the yielded surface energy has been effectively reduced to a level lower than PTFE. The synthesized polymer is a nonhalogenated low surface-energy material with potential applications. ? 2021 |
