Abu Bakar etc. are prepared for Yin Na in natural rubber and modified natural rubber respectively by photo-induction guiding method
Rice corpuscles, but research shows that, with the extension of light application time, the molecular weight of natural rubber constantly reduces (N.H.H.Abu
Bakar,J.Ismail,M.Abu Bakar.Materials Chemistry and Physics 2007,104,276–283.；
N.H.H.Abu Bakar,J.Ismail,M.Abu Bakar.Reactive&Functional Polymers 2010,70,
168-174.)。
Rathnayake etc. in the natural rubber of foaming, is prepared for Nano silver grain by reduction of sodium citrate method, should
Method preparation process it is cumbersome and used extra reducing agent sodium citrate (W.G.I.U.Rathnayake, H.Ismail,
A.Baharin,A.G.N.D.Darsanasiri,Sanath Rajapakse.Polymer Testing,2012,31,586–
592.)。
