indicating that the control sample can only block a portion of UV light. In the visible spectrum (400–780 nm), imine epoxy vitrimers showed lower transmission compared to the Control. This phenomenon is caused by the presence of imine groups in the vitrimer network, which act as chromophores...
In a water molecule, the oxygen atom has two lone pairs of electrons, each of which can act as a hydrogen bond acceptor. The two hydrogen atoms in water can each be “donated” to another acceptor atom (such as the oxygen atom on another water molecule). Water molecules are bent at an...
