In　this　study,　a　Norland　optical　adhesive　68　(NOA68)　film,　approximately　2.2　mu　m　thick,　was　manufactured　using　ultraviolet　solidified　NOA68　in　apparatus　manufacturing　film　on　the　inwall　of　a　capillary　copper　pipe,　developed　in　our　laboratory.　The　roughness　of　the　inwall　of　capillary　copper　pipe　was　improved　from　Ra　=　0.766　to　0.204　mu　m　and　the　contact　angle　was　improved　from　approximately　96　degrees　to　55　degrees,　increasing　hydrophilicity.　Polymerase　chain　reaction　experiments　indicated　that　the　ratio　of　work　pressure　in　the　microfluidic　chip　before　modification　to　that　after　modification　was　2.71/1,　indicating　that　the　extension　efficiency　increased.　Our　results　provide　a　basis　for　the　construction　of　a　microform　chip　based　on　function　integration.
