Application

2,2-Dimethoxy-2-phenylacetophenone (DMPA) can be used as a photoinitiator:
  • For the photopolymerization of methacrylate monomers in thick sections(~2mm).
  • In the preparation of UV-curing silicone rubber with excellent mechanical properties and thermal stability via thiol-ene reaction.
It can also be used as a starting material to prepare a water-soluble supramolecular-structured photoinitiator which is more efficient than DMPA.

Active biofluid management is central to the realization of wearable bioanalytical platforms that are poised to autonomously provide frequent, real-time, and accurate measures of biomarkers in epidermally-retrievable biofluids (e.g., sweat). Accordingly, here, a programmable epidermal microfluidic valving system is devised

The preparation and the thermal and mechanical characteristics of lignin-containing polymer biocomposites were studied. Bisphenol A glycerolate (1 glycerol/phenol) diacrylate (BPA.GDA) was used as the main monomer, and butyl acrylate (BA), 2-ethylhexyl acrylate (EHA) or styrene (St) was used as

Cells in tissues or biofilms communicate with one another through chemical and mechanical signals to coordinate collective behaviors. Non-living cell mimics provide simplified models of natural systems; however, it has remained challenging to implement communication capabilities comparable to living cells.

ACS applied materials & interfaces, 8(47), 32504-32511 (2016-11-05)
Conjugated polymers containing long-chain alkyl side groups for solubility are generally unstretchable: large strain induces crack formation, fracture, or plastic deformation. When the polymers are stretched to reorient the conjugated chains along the stretching direction, high dichroic ratio is observed
