The hybrid technique of aerosol jet printing and ultraviolet (UV) laser direct writing was developed for 2D patterning of thin film UV curable polydimethylsiloxane (PDMS). A dual atomizer module in an aerosol jet printing system generated aerosol jet streams from material components of the UV curable PDMS individually and enables the mixing in a controlled ratio. Precise control of the aerosol jet printing achieved the layer thickness of UV curable PDMS as thin as 1.6 μm. This aerosol jet printing system is advantageous because of its ability to print uniform thin-film coatings of UV curable PDMS on planar surfaces as well as free-form surfaces without the use of solvents. In addition, the hybrid 2D patterning using the combination of UV laser direct writing and aerosol jet printing achieved selective photo-initiated polymerization of the UV curable PDMS layer with an X-Y resolution of 17.5 μm.The hybrid technique of aerosol jet printing and ultraviolet (UV) laser direct writing was developed for 2D patterning of thin film UV curable polydimethylsiloxane (PDMS).

使用 UV 激光直写和 UV 固化聚二甲基硅氧烷的气溶胶喷射打印的混合 2D 图案化

开发了气溶胶喷射印刷和紫外 (UV) 激光直写的混合技术，用于薄膜 UV 固化聚二甲基硅氧烷 (PDMS) 的 2D 图案化。气溶胶喷射打印系统中的双雾化器模块从可紫外线固化的 PDMS 的材料组分中单独生成气溶胶喷射流，并能够以受控比例进行混合。对气溶胶喷射印刷的精确控制使 UV 可固化 PDMS 的层厚度薄至 1.6 μm。这种气溶胶喷射印刷系统具有优势，因为它能够在不使用溶剂的情况下在平面和自由曲面上印刷均匀的 UV 可固化 PDMS 薄膜涂层。此外，使用紫外激光直写和气溶胶喷射印刷相结合的混合 2D 图案实现了紫外光固化 PDMS 层的选择性光引发聚合，XY 分辨率为 17.5 μm。气溶胶喷射印刷和紫外 (UV) 激光直射的混合技术写入是为薄膜 UV 固化聚二甲基硅氧烷 (PDMS) 的 2D 图案化而开发的。气溶胶喷射打印系统中的双雾化器模块从可紫外线固化的 PDMS 的材料组分中单独生成气溶胶喷射流，并能够以受控比例进行混合。对气溶胶喷射印刷的精确控制使 UV 可固化 PDMS 的层厚度薄至 1.6 μm。这种气溶胶喷射印刷系统具有优势，因为它能够在不使用溶剂的情况下在平面和自由曲面上印刷均匀的 UV 可固化 PDMS 薄膜涂层。此外，结合使用紫外激光直写和气溶胶喷射印刷的混合 2D 图案实现了紫外光固化 PDMS 层的选择性光引发聚合，XY 分辨率为 17.5 μm。
