As renewable resource

natural rubber (NR) has been widely used in many applications including aerospace

war industry and medical treatment due to its excellent comprehensive performances. However

the poor resistances to oil

organic solvent

thermo-oxidative ageing and ultraviolet rays

which drives from its nonpolar and unsaturated chemical chain structures

NR is underperformed in some special fields. Therefore

the modification of NR has attracted great attention in both academia and industry. Herein

the progresses achieved in the recent years are summarized from three aspects

i. e. chemical modification

bleeding modification and organic fillers-filled modification.
