Abstract:
      The natural latex films reinforced by graphene oxide，bacterial cellulose and nano-microcrystalline cellulose were studied，and the ultra-thin condom was trial produced with nano-microcrystalline cellulose latex.The results showed that，the film reinforced by graphene oxide had black spots.When the amount of graphene oxide was large，the film was easy to shrink and crack，and its elasticity was poor and strength was low.The film reinforced by bacterial cellulose was rough and had white spots， and its tensile strength and tear strength would generally be reduced，and the reinforcement effect of bacterial cellulose was poor.The modulus，tensile strength，elongation at break and tear strength of the film reinforced by nano microcrystalline cellulose A were high，and the reinforcing effect of nano microcrystalline cellulose A was obvious.When the dosage of nano microcrystalline cellulose A and B was 0.2 phr，the natural latex ultra-thin condom which was trial produced by nano microcrystalline cellulose A and B had good appearance and high tensile strength.
