The sioxane network is controlled using a crosslink of desulfurized aldehyde

In a current study, researchers are working to develop a network of desulfurized desuldide silicone that does not require a metal catalyst.
traditional silicone elastic system preparation methods are mainly focused on platinum and tin-based curing chemicals. For environmental and cost reasons, there is a need to find ways to find silica, which does not require the use of heavy metals retained in elastomer after curing,

. A new work describes a network of desulfurized silica, which is easily formed between thiol-modified silica monomers and polymers and aromatic aldehydes in the presence of acids and does not require a metal catalyst. Chemical and physical interlinking is used to independently manipulate elastomer properties.
sulfur desalination of aromatic aldehyde as an alternative, metal-free, organic curing
due to differences in network structure, the subtle differences in aromatic aldehydes used to cross-linked siloxane lead to large changes in mods. Using these associations, silicone mechanical properties can be customized from very soft gels to more rigid elastomers. The product is very stable for hydrolysis and thermal stress, which is surprising given the normal sensitivity of sioxane to acid catalytic reactions. The use of easy-to-use aromatic aldehyde as an alternative to metal-free organic curing of sulfur desalination provides an attractive way to optimize polymer performance.
