Abstract
Acrylic acid was used to investigate the capabilities of novel two-dimensional molecular space with regular amino groups (layered aminopropylsilica, ATMS-DS) on influencing and controlling molecular reaction processes. The acrylic acid was regularly fixed in the layer structure of layered aminopropylsilica through the formation of amide between carboxyl of acrylic acid and amino groups of layered aminopropylsilica. The acrylic acid regularly fixed in layered aminopropylsilica was completely polymerized to form a novel organic-inorganic nanocomposite material named as layered polyacryl-amidepropylsilica (ATMS-PAA) with monolayers of polyacrylamide in layer space of layered aminopropylsilica without initiator after being heated at 100 °C for 24 h. It was found that the polymerization of acrylic acid was facilitated in the novel two-dimensional molecular space with regular amino groups compared with free space. The polymeric structure of ATMS-PAA was also found to be decided by the regular structure of layered aminopropylsilica. The novel two-dimensional molecular space with regular amino groups in structure showed a potential of influencing and controlling molecular reaction processes. The formation of a novel hybrid organic-inorganic nanocomposite material (layered polyacrylamidepropylsilica) is also interesting for the research of polymer nanocomposite materials.
