Typically, these patches are crafted using polymer-based materials, primarily due to their processability and suitability for producing thin patches.
Material and Methods Four distinct materials, namely PVA, PVP, GLY, and DW, were employed in the production of the transdermal patches.
These materials were combined in 17 different ingredient ratios to create the patches.

So adding the RE can improve a series of metal materials properties such as good grain refinement, purification organizations and metamorphism [5-6].
Recycled impure copper contains of many impurities, so its conductivity is low, the use of RE on the purification and degassing of copper can increase the conductivity of materials.
With increase of content of RE, the effect on grain refinement of materials by RE decreased, while the residual liquid RE in copper increased which played the same role with impurities.
So the high content of RE in materials can low conductivity.

Introduction As one of important industrial materials, Epoxy resin has many good properties such as excellet interfacial adhesion ,corrosion resistance,electric insulating and high strength[1].Although it has become an indispensable material[2] in industrial areas, the limitation[3] is still exist for its poor toughness in its practical application.while it is easy to improve the toughness by using traditional way ,it always cause the decreasing in the flexural strength and tensile strength.The toughness of material can be improved by the introduction of the hyperbranched polymer which can absorb energy by the shape change itself and cavitation,and then the crack fracture was hindered[4].Hyperbranched polyesters (HBPS) has been comprehensively studyed by researchers abroad mainly in toughness and toughening mechanism,the curing behavior and UV curing and have get some good achievements.our internal reseachs is late in this area by contrast and mainly focus in the influence of HBPS
Experimental and Methods 1.1 Materials E-51 Epoxy resin was supplied by The synthetic Materials Research Institute of Tianjin.4,4'-diaminodiphenylmethane (DDM)(AR) was obtained from Chemical Reagent corporation of BeiJing.Triphenylphosphine was purchased from Tianjin Institute of chemical reagents.The hyperbranched polyphosphate ester(HPPE) was synthesized in our lab. 1.2 Characterization The mechanical properties of Epoxy resin were measured by electronic universal tester RGT-5(drawing rate was 10mm/min and testing temperature was 23℃).The unnotched impact strength of samples was carried out using pendulum shock testing machine.
